Statistics

1. See the two data sets for independent samples:

Sample 1 Sample 2

n = 50 n = 35

xbar = 13.6 xbar = 11.6

Pop SD = 2.2 Pop SD = 3.0

What are the point estimates and 95% confidence intervals for these samples?

2. Consider this hypothesis test for a sample of 75 units with a population standard deviation of 10.

H0: Mean = 22

Ha: Mean =/= 22

If the sample mean is 23, what is your conclusion for this hypothesis test with an alpha value of .01?
