7. Assume that the average Systolic blood pressure for adults age 50-54 is 125 mmHg with a tandard deviation of 5 mmHg. It is known that Systolic blood pressure is not normally istributed. A sample of 25 adult Systolic blood pressure measurements are taken from the opulation. What type of test would be appropriate for this example to see if the sample results are different from the average diastolic blood pressure measurements? I.A one-sample t test because the data are not normally distributed. II. A one-sample z test because the data are not normally distributed. III. A 95% confidence interval using a critical t statistic. IV. I and III B) I only C) III only D) II only

27. Assume that the average Systolic blood pressure for adults age 50-54 is 125 mmHg with a standard deviation of 5 mmHg. It is known that Systolic blood pressure is not normally distributed. A sample of 25 adult Systolic blood pressure measurements are taken from the population. What type of test would be appropriate for this example to see if the sample results are different from the average diastolic blood pressure measurements? I.A one-sample t test because the data are not normally distributed. II. A one-sample z test because the data are not normally distributed. III. A 95% confidence interval using a critical t statistic. IV. I and III B) I only C) III only D) II only 28. The weights at birth of five randomly chosen baby giraffes were 111, 115, 120, 103, and 106 pounds. Assume the distribution of weights is normally distributed. Find a 95% confidence- interval for the mean weight of all baby giraffes. Use technology for your calculations. Give the confidence interval in the form "estimate ± margin of error." Round to the nearest tenth of a pound.
