The following 10 numbers were drawn from a population:
5 7 7 10 10 10 11 12 12 13
a) Calculate the 95% confidence interval for the population mean
b) Is it likely that these numbers came from a population with a mean of 13? Explain
c) Calculate t and decide to reject or fail to reject the null hypothesis. mu=13 using a two-tailed test and at an alpha of .05

mean.
b) 95% of all possible population means will be included in the
interval.
