According to a survey, the mean height for men is 68.6 inches. In a sample of 320 men between the ages of 60 and 69 , the mean height was x¯ = 68.5 inches. Public health officials want to determine whether the mean height μ for older men is less than the mean height of all adult men. Assuming the population standard deviation to be σ = 2.85 inches, compute the value of the test statistic. 429.95 −0.63 0.63 0.74

The heights are measured for the simple random sample of 9 supermodels. They have a mean height of 66.6 inches and a standard deviation of 1.9 inches. A sample is taken of the heights of 40 women who are not supermodels and they have heights with a mean of 66.3 inches and a standard deviation of 2.3 inches. Use a 0.10 significance level to test the claim that the mean height of supermodels is greater than the mean height of women who are not supermodels. Assume that the two samples are independent simple random samples selected from normally distributed populations. Do not assume that the population standard deviations are equal. 2 Click the icon to view the table of critical values. (1) sufficient evidence that the mean height of supermodels is greater than the mean height of women who are not supermodels. 2: Critical Values

When 14 different second-year medical students measured the systolic blood pressure of the same person, they obtained the results listed below (in mmHg). Assuming that the population standard deviation is known to be 10mmHg, use a 0.05 significance level to test the claim that the mean blood pressure level is less than 140mmHg. Hypertension is defined to be a blood pressure level that is too high because it is 140mmHg or greater. Assume the blood pressure levels are normally distributed. Based on the hypothesis test results, can it be safely concluded that the person does not have hypertension?

H0 : µ = 140 versus H1 : µ 6= 140 B. H0 : µ = 140 versus H1 : µ > 140 C. H0 : µ = 140 versus H1 : µ < 140 (b) Identify the test statistic. z = (Round the final answer to two decimal places as needed. Round all intermediate values to two decimal places.) (c) Identify the P-value. The P-value is. (Round to three decimal places as needed.) (d) What is the final conclusion? A. Fail to reject H0. There is sufficient evidence to support the claim. B. Reject H0. There is not sufficient evidence to support the claim. C. Reject H0. There is sufficient evidence to support the claim. D. Fail to reject H0. There is not sufficient evidence to support the claim. (e) Can it be safely concluded that the person does not have hypertension? Yes No

A simple random sample from a population with a normal distribution of 98 body temperatures has x¯ = 98.20◦F and s = 0.63◦F. Construct a 90% confidence interval estimate of the standard deviation of body temperature of all healthy humans. Is it safe to conclude that the population standard deviation is less than 1.20◦F ? 11 Click the icon to view the table of Chi-Square critical values. ◦F < σ < ◦F (Round to two decimal places as needed.) Is it safe to conclude that the population standard deviation is less than 1.20◦F ? A. This conclusion is not safe because 1.20◦F is in the confidence interval. B. This conclusion is safe because 1.20◦F is outside the confidence interval. C. This conclusion is not safe because 1.20◦F is outside the confidence interval. D. This conclusion is safe because 1.20◦F is in the confidence interval.
