survey of 80 men found that an average amount spent on St. Patrick's day of $48 with a standard deviation of $20. A similar survey of 75 women found they spent an average of $42 with a standard deviation of $16. When testing the hypothesis (at the 10% level of significance) that men spend more than women on St. Patrick's day, if the test statistic is 2.07 and the critical value is 1.28 then what is your conclusion concerning the null hypothesis? Reject the null hypothesis Fail to reject the null hypothesis
