Researchers believe the average is different in a particular city and draw a sample of 24 to test this hypothesis. The sample mean is $3,275 and the sample standard deviation is $581. If they use a two-tailed t test with an alpha level of 0.01, what is the value of the t statistic; what is the critical value from the t table; and what is their decision on the null hypothesis? 0 t = 3.53; critical t = 2.80; reject O t = 1.13; critical t = 3.77; fail to reject O t = 3.53; critical t = 3.77; fail to reject O t = 1.13; critical t = 2.80; reject
