#14 A random sample of 15 observations from the first population revealed a sample mean of 350 and a sample standard deviation of 12. A random sample of 17 observations from the second population revealed a sample mean of 342 and a sample standard deviation of 15. At the .10 significance level, is there a difference in the population means?

Step 1 State the Null and Alternative Hypothesis

H0: 1 = 2
H1: 1 2

Step 2 Select the Significance Level

= 0.10

Step 3 = n is < than 30, so we use "T" Test Statistics

Step 4 = Find the Critical Value of "T" statistic use the Two Tail Test.

Critical Value= 2.749985 // formula =TINV(0.01,15+17-2)
SP2 = 187.2 // formula =((15-1)*12^2+(17-1)*15^2)/(15+17-2)
t= 1.650563 // formula =(350-342)/SQRT(J20*(1/15+1/17))

Step 5 = Solve Absolute Value of Test Statistic great than Critical Value then reject H0. Otherwise do not reject H0. (formula used // =IF(1.65>2.75,"reject H0","Do not reject H0")

Based on the decision: Do not reject H0.
