Discussion:
Q1: James and John want to see who catches the most fish on their fishing trips. It is hypothesized that the two brothers catch the same number of fish. James catches an average of 20 fish in 12 fishing trips with a standard deviation of 3 fish and John catches an average of 24 fish in 15 fishing trips with a standard deviation of 5 fish. Is there any evidence to support the claim that John catches more fish at the =.05 level? Remeber to use all four steps.
Q2: James and John want to make a 99% confidence interval for James fish minus Johns fish. James carches an average of 30fish in 15 fishing trips with a standard deviation of 5 fish and John catches an average of 24 fish in 9 fishing trips with a standard deviation of 15 fish. Remember to use all four steps to confidence intervals
