Question

Suppose that in Problem 1 only 25 of 36 randomly selected family caregivers
responded, so we have the following data:
55 53 47 47 49 43 47 40 48 41 44 51 48
43 50 49 47 42 42 47 47 49 46 46 43
Assuming that these data come from a population that has a normal distribution,
(a) Determine a 99% confidence interval for the mean ages of all US caregivers.
(b) Determine a one-sided lower and one-sided upper 99% confidence interval for
the mean ages of all US caregivers.

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
