Scores turned in by an amateur golfer at the, №17887889, 03.11.2021 07:31

s = 2.07

The mean and standard deviation for the year 2018 scores is:

                                     2018

Mean                                 76

Standard deviation       2.07

The mean for 2019 scores is:

Scores turned in by an amateur golfer at the, №17887889, 03.11.2021 07:31

Scores turned in by an amateur golfer at the, №17887889, 03.11.2021 07:31

The standard deviation for 2019 scores is:

Scores turned in by an amateur golfer at the, №17887889, 03.11.2021 07:31

Scores turned in by an amateur golfer at the, №17887889, 03.11.2021 07:31

Scores turned in by an amateur golfer at the, №17887889, 03.11.2021 07:31

s = 5.26

The mean and standard deviation for the year 2019 scores is:

                                     2019

Mean                                 76

Standard deviation       5.26

Difference: Both the two years have the same mean but the 2019 scores have higher variation as compared to 2018 scores.

Thus, the variation in scores was higher in 2019.

Step-by-step explanation:

The mean for 2018 scores is:

M ean ( \overline X) = \dfrac{\sum x_i}{n}

M ean ( \overline X) = \dfrac{74 + 78+79+77+75+73+75+77}{8}

M ean ( \overline X) = \dfrac{608} {8}

\mathbf{M ean ( \overline X) = 76}

The standard deviation for 2018 scores is:

s = \sqrt{\dfrac{\sum ( x_i - \bar x)^2}{n- 1}  }

s = \sqrt{\dfrac{ ( 74 -76)^2+( 78 -76)^2+( 79 -76)^2+...+( 73 -76)^2+( 75 -76)^2+( 77 -76)^2}{8- 1}  }

s = \sqrt{\dfrac{30}{7}  }

s = 2.07

The mean and standard deviation for the year 2018 scores is:

                                     2018

Mean                                 76

Standard deviation       2.07

The mean for 2019 scores is:

M ean ( \overline X) = \dfrac{\sum x_i}{n}

M ean ( \overline X) = \dfrac{71 + 70+75+77+85+80+71+79}{8}

M ean ( \overline X) = \dfrac{608} {8}

\mathbf{M ean ( \overline X) = 76}

The standard deviation for 2019 scores is:

s = \sqrt{\dfrac{\sum ( x_i - \bar x)^2}{n- 1}  }

s = \sqrt{\dfrac{ ( 71 -76)^2+( 70 -76)^2+( 75-76)^2+...+( 80 -76)^2+( 71 -76)^2+( 79 -76)^2}{8- 1}  }

s = \sqrt{\dfrac{194}{7} }

s = 5.26

The mean and standard deviation for the year 2019 scores is:

                                     2019

Mean                                 76

Standard deviation       5.26

Difference: Both the two years have the same mean but the 2019 scores have higher variation as compared to 2018 scores.

Thus, the variation in scores was higher in 2019.

Volume of rectangular prism=length * width * height

Given,

length=3/8cm

breadth=5/8cm

height=7/8cm

therefore volume=(3/8)*(5/8)*(7/8)

                           =105/512 cm3
