(1.4328, 1.622)
Claim is supported by evidence.
Step-by-step explanation:
Given that a recent study was conducted to determine the curing efficiency (time to harden) of dental composites (resins for the restoration of damaged teeth) using two different types of lights.
Let X be the halogen and y the Luxomax light
(Two tailed test)
we are given data as:
Group Group One Group Two
Mean 5.3500 3.9000
SD 0.7000 0.8000
SEM 0.2214 0.2530
N 10 10
The mean of Group One minus Group Two equals 1.4500
Std error for difference = 0.336
Test statistic t=4.3135
df = 18
p value = 0.0004
Since p <0.01 at 1% level, reject H0
There is significant difference and hence the claim is valid.
There is evidence to support this claim at 1% significance level
Margin of error =1.172
99% confidence interval =

B. use a familiar concept to communicate an idea
Explanation:
Basically, Passage 2 states the hypothesis that spotted green pigeon is a descendant of an island hopping bird and throughot the article, it provides evidence for this statement.
The discovery is that, since the DNA found in a green pigeon's feather was fragmented and they had to analyze only parts of it, the bird had an unique sets of DNA which distinguish it from other members of the pigeon species.
These analyzed parts of DNA are refered to as "mini barcodes".
Since target audience for this article might not be fully familiar with the concept and functions od DNA, researchers used a more familiar concept of barcodes as an analogy to communicate their idea and explain their discovery.
The answer is: teller, loan officer, and tax preparer
Teller act as a front liner on banks who deals directly with the customers. The main job of a teller is to assist the people in making their transaction in the bank.
The main duty of a loan officer is to finds potential clients who need capital injection and assists them in acquiring loans.
Tax prepares help their clients in examining their tax report in other to find out the items that can be used as tax returns.
Sucrose is disaccharide composed of glucose linked to galactose is the statement that is not true about carbohydrate structures.
Sucrose is a disaccharide, which means it includes two units of monosaccharide linked together. Each type of disaccharide is composed of different units.
Maltose : Two units of glucoseLactose: One unit of glucose and one of galactose.In the case of Sucrose, this is composed of one unit of glucose and one unit of fructose. This disaccharide can be found in common sugar, this means the statement "e" is false because sucrose does not have galactose, instead galactose can be found in lactose, which is a different disaccharide.
