Question 6

Given the table from the textbook, Example 5.1, that is shown here, what is the probability of choosing a girl that is either 6 or 7 years old?

Give the answer as a decimal to the hundredths place. And always round up, so 0.956782 is 0.96.

Question 12

The mean number of push-ups performed in a cross-fit class in the population isu with a standard deviation of 6. Researchers are interested in whether a sample of36 individuals in a new cross-fit class perform less push-ups than the population average. What is the probability that the mean number of push-ups performed by this new cross-fit class is less than 1 unit below the the population mean?

Give the answer as a decimal point to the hundredths place; for instance, 1/2 is 0.50.

Answer

Question 13

The mean number of push-ups performed in a cross-fit class in the population is 56 with a standard deviation of 16. Researchers are interested in whether a sample of36 individuals in a new cross-fit class perform a different amount ofpush-ups than the population average. What is the probability that the mean number of push-ups performed by this new cross-fit class is between 53 and 58 push-ups?

Give the answer as a decimal point to the hundredths place; for instance, 1/2 is 0.50.

Question 15

In a study of 120 post-menopausal women on hormone replacement therapy (HRT), there was a mean systolic blood pressure of 131 mmHg, with a standard deviation of 16.5. Calculate a 95% confidence interval for the true mean SBP.

In the first blank, put the minimum value of the 95% confidence interval; in the second blank, put the maximum value of the 95% confidence interval. Round both to the hundredths place.

For instance, if the 95% confidence interval is (120.4567, 140.1234), then enter 120.46 in the first blank and 140.12 in the second blank.
