What is the correct choice for question 6

Question 6 1 pts The means of the number of revolutions per minute of two competing engines are to be compared. Thirty engines are randomly assigned to be tested. Both populations have normal distributions. The Table below shows the results. Does the data indicate that Engine 2 has higher RPM performance than Engine 1? Test at a 5% level of significance. Sample Mean Number of Engine Population Standard RPM Deviation 1,500 50 N D 1,600 70 Since the p value is nearly zero is less than the significance level of 0.05, Engine 2 has a higher rpm performance one has a higher rpm performance level Both engines have the same engine performance level
