Assume that you have a sample of n 1 equals 8n1=8, with the sample mean upper x overbar 1 equals 40x1=40, and a sample standard deviation of upper s 1 equals 7s1=7, and you have an independent sample of n 2 equals 4n2=4 from another population with a sample mean of upper x overbar 2 equals 38x2=38 and the sample standard deviation upper s 2 equals 6s2=6. assuming the population variances are equal, at the 0.010.01 level of significance, is there evidence that mu 1 greater than mu 2μ1> μ2? a) find the test statistic. b) find the p-value. c) choose the correct conclusion below. a. do not rejectdo not reject upper h 0h0. there is insufficientinsufficient evidence that mu 1 greater than mu 2μ1> μ2. b. do not rejectdo not reject upper h 0h0. there is sufficientsufficient evidence that mu 1 greater than mu 2μ1> μ2. c. rejectreject upper h 0h0. there is insufficientinsufficient evidence that mu 1 greater than mu 2μ1> μ2. d. rejectreject upper h 0h0. there is sufficientsufficient evidence that mu 1 greater than mu 2μ1> μ2.

You just purchased two coins at a price of $670 each. because one of the coins is more collectible, you believe that its value will increase at a rate of 7.1 percent per year, while you believe the second coin will only increase at 6.5 percent per year. if you are correct, how much more will the first coin be worth in 15 years?
