Assume that the blood pressure in Qatari population are normally distributed with standard deviation 25 mmHg. The doctor would like to test the null hypothesis H0: μ = 110 mmHg versus H1: μ ≠ 110 mmHg for a sample of n=16 persons. The acceptance region is 100≤ x̄ ≤ 122. α = P(type I error) is closest to:

The systolic blood pressure (SBP) of a certain population is normally distributed with standard deviation 6 mmHg. A sample of 24 members of this population was found to have an average SBP of 122 mmHg. Find a 90% confidence interval for the population mean. Round the endpoints to the nearest integer. Confidence interval is: The average starting salaries for 48 graduates with a certain major was $42061. The standard deviation for all graduates with that major was $8318. Give the...

From a nationwide study, we know that the mean diastolic blood pressure is 60 mm gH for children aged 5-6 years of age, and that the measurements are normally distributed. Blood pressure measurements were taken on 13 children aged 5-6 years living in a specific community to determine whether their living conditions resulted in a difference in mean blood pressure. For these children the average diastolic blood pressure was found to be 55 mm Hg with standard deviation 7.5 mm...

A sample of size 194, taken from a normally distributed population whose standard deviation is known to be 9.50, has a sample mean of 91.34. Suppose that we have adopted the null hypothesis that the actual population mean is greater than or equal to 93, that is, H0 is that μ ≥ 93 and we want to test the alternative hypothesis, H1, that μ < 93, with level of significance α = 0.05. a) What type of test would be...
