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?
