36If a sample of n100 is drawn from a population whose stand

36.If a sample of n=100 is drawn from a population whose standard deviation is 100, then the standard error of the mean equals

a. 10

b. 100

c. 1,000

d. 10,000

37. The confidence interval estimate of the population mean will be wider for a 95% confidence level than for a 90% confidence level.

True

False

Solution

36.

standard error = s / sqrt(n) = 10 [OPTION A]

*******************

37.

Greater confidence levels are wider.

Thus, TRUE.
