A survey of 550 male managers and 650 female managers was conducted. All 1,200 managers identified whether, for each of six characteristics, the characteristic is important to consider when hiring a new employee. For each of the six characteristics, the percent of managers surveyed who identified that characteristic as important to consider is given in the following table.

Step-by-step answer

P Answered by PhD

Correct option is (B). 20%.

Step-by-step explanation:

The number of managers is, 1200.

The percentage of managers who identified work experience as an important characteristic to consider is, P (W) = 72%.

The percentage of managers who identified appropriate attire and behavior as an important characteristic to consider is, P (AB) = 55%.

Compute the number of managers who identified work experience as an important characteristic to consider as follows:

$n(W)=1200\times P(W)\\=1200\times\frac{72}{100}\\=864$

Compute the number of managers who identified appropriate attire and behavior as an important characteristic to consider as follows:

$n(AB)=1200\times P(AB)\\=1200\times\frac{55}{100}\\=660$

Compute approximately what percent greater is P (W) than P (AB) as follows:

$P(WAB)=\frac{n(W)-n(AB)}{1200}=\frac{864-660}{1200}=\frac{204}{1200}=0.17\approx0.20$

Thus, the number of managers surveyed who identified work experience as an important characteristic to consider was approximately 20% percent greater than the number who identified appropriate attire and behavior as an important characteristic to consider.

Correct option is (B).

Will give dont answer unless you know the question 1(multiple choice worth 3 points) (06.01 hc) a team of scientists altered the dna of pseudomonas bacteria. the bacteria thus developed had the ability to eat up oil. what could be the likely impact of this biotechnology on the environment and the society? a. toxic gases would be released, causing large-scale pollution. b. damage to marine flora and fauna due to oil spills could be prevented. c. the consumption of nonrenewable energy sources would be increased. d. the process of oil exploration

1) Since the bacteria has the ability to eat up oil it will help prevent further damage to the marine flora and fauna due to oil spills. (B)
2) Woolly Mammoth lived during the ice age as the weather became warmed their fur along with the change in their food supply may have caused their deaths. Based on the options given, shedding of fur may have helped them from going extinct.
3)Since the student wants to compare how thermal energy is transferred between spoons the best way to do that is to place an ice cube on each spoon and record the rate of melting of the cubes. Placing both spoons are room temperature and recording the change in temperature in each will not assist in answering his question. And measuring the change in the weight of the spoons after placing them in the freezer will not provide data in regards to the transfer of thermal energy.
4) Meiosis is defined as a type of cell that once it divides it results in four daughter cells, while mitosis is defined as the type of cell that results in two daughter cells and each has the same number and kind of chromosomes as the parent cell. Skin cells undergo mitosis as such, the answer is B, both characteristics represent mitosis.
5)A Punnett square is a diagram in the shape of a square that is used to predict an outcome of a cross breed. In other words, it is used to determine the probability that an offspring having a set genotype. In a Punnett square, a lower case letter indicates a recessive allele while an upper case letter represents dominant allele.
6) The Arctic is an environment that is covered in ice based on this animals are more likely to survive if they have white skin or fur as it would be easier for them to blend with the environment. Having black fur would make them stand out even more due to the environment.
7) Homozygous means that the gene has identical alleles on both homologous chromosomes. it is represented by two capital letters for a dominant trait as such, RR is the correct answer.
8) Since the question is referring to skin cancer specifically, the only option is A, avoid staying outdoors when the sun is strongest. Skin cancer is caused by a mutation in the cells in which UV light affects the cells of the skin.
9) since the chart is not given I am unable to answer the question but you mentioned that you knew the answer.

You have been hired as a field assistant for a researcher interested in the evolution of flower characteristics in orchids. Complete an experiment that determines whether color, size, shape, scent, or amount of nectar is the most important factor in attracting pollinators to a particular species. Assume that you can change any flower s color with a dye and that you can remove petals or nectar stores, add particular scents, add nectar by injection, or switch parts among species by cutting and gluing. Match the terms in the left column to the appropriate

$\text{Present a flower with one characteristic changed to the normal pollinator. }$ $\text{As a control, present a flower with no characteristics changed to the normal pollinator}$

$\text{Record any measure of pollination success}$

$\text{Repeeat for flowers with other characteristics changed}$

$\text{Analyze the data to determine which altered characteristics affect pollination }$ $\text{success the most. This characteristic will be the result of the experiment.}$

Explanation:

The missing information is attached below.

$\text{Present a flower with one characteristic changed to the normal pollinator. }$ $\text{As a control, present a flower with no characteristics changed to the normal pollinator}$

For the control, you'll need something you're already familiar with. In this scenario, a normal flower with no changes in characteristics is the best control. And if no data is accessible, you still have data on the success rate of a typical flower, which can be used as a guideline. And, for the initial configuration, you can only adjust one characteristic so it would be easier to maintain track of and analyze the data gathered.

$\text{Record any measure of pollination success}$

Since the aim of your experiment is to examine the influence of flower characteristics on pollination performance, you should keep track of the active pollination events. To have more accurate results, this would require listing the total number of plants that were to be pollinated.

$\text{Repeeat for flowers with other characteristics changed}$

Once you've completed the initial examination, you'll need to run tests on various characteristics to see whether they have some impact on pollination performance. To see the importance of different characters on pollination, change only one trait in flowers; if you'd like to research combined results, create pairs and change them together.

$\text{Analyze the data to determine which altered characteristics affect pollination }$ $\text{success the most. This characteristic will be the result of the experiment.}$

Your outcome is also the one that has gotten the most constructive or negative reviews. If some changed characteristic significantly affected the number of pollination efficiency, that is your outcome, because that is what you can mention as a good result and pollination enhancer.
