The label on a can of sardines indicates the can contains 10 sardines. You open up 100 cans and record the number of fish in each can. You find the sample average is 9.5 and sample standard deviation is 1. Calculate and report the absolute value of the test statistic for the hypothesis test (this is a test involving a single mean) where the null hypothesis is that the population average is 10.
Do you find strong enough evidence to reject the null that the 100 cans were drawn from a population where the mean is 10? yes/no
