A credit card company wants to test the hypothesis that its account holders spend an average of $100 per month at gasoline stati
ons. They take a sample of 1000 accounts and find an average spend of $115 with a standard deviation of $41. Conduct this hypothesis test with a .01 level of significance. What is the test statistic? Answer to two decimal places. Hint: this is a two-tail test.
Sorry I’m not sure if this is much help but the answer is undefined because (y2-y1)/(x2-x1) would equal 7/0 for your slope therefore there is no equation for these points
