Question

A college biology lab selected 65 women and 65 men at random and recorded their body temperatures (in degrees Fahrenheit). The distributions of their temperatures are shown below.Which statement gives an accurate comparison of the body temperatures of women and men shown?

Question 5 options:

1.)The mean body temperature for women is less than for men and women's temperatures vary more than men's temperatures.
2.)The mean body temperature for women is greater than for men and women's temperatures vary less than men's temperatures.
3.)The mean body temperature for women is less than for men and women's temperatures vary less than men's temperatures.
4.)The mean body temperature for women is greater than for men and women's temperatures vary more than men's temperatures.

Answer 1

Answer: number 4

The mean body temperature for women is greater than for men and women's temperatures vary more than men's temperatures.

Step-by-step explanation: did the test got 100%

Answer 2

4.) The mean body temperature for women is greater than for men and women's temperatures vary more than men's temperatures.

Explanation:

Given the two histograms of men's and women's body temperature, you want a comparison of the mean and variation.

Mean

A calculator shows the mean of each distribution to be ...

men: 97.92

women: 98.17

The mean temperature of women is higher.

Variation

The calculator shows the standard deviation to be ...

men: 0.727

women: 0.762

The variation of women's temperatures is greater.

The best description is ...

4.) The mean body temperature for women is greater than for men and women's temperatures vary more than men's temperatures.

Additional comment

For our calculations, we used the left end of the interval as representative of the values in the interval. If you want to use the center, you can add 0.25 degree to each of the means.
