Is the assumption of equal variances reasonable? Why or why not? Yes, because the ratio of the larger variance to smaller variance is less than 3. Yes, because the ratio of the larger variance to smaller variance is more than 3. O No, because the ratio of the larger variance to smaller variance is not equal to 1. O No, because the ratio of the larger variance to smaller variance is less than 3. O No, because the ratio of the larger variance to smaller variance is more than 3. (b) Do the data indicate that there is a difference in the average number of completed passes for the two quarterbacks? Test using a = 0.05. (Use Hy for the population mean for Alex Smith and Ny for the population mean for Joe Flacco.)
(b) Do the data indicate that there is a difference in the average number of completed passes for the two quarterbacks? Test using a = 0.05. (Use w, for the population mean for Alex Smith and uy for the population mean for Joe Flacco.) State the null and alternative hypotheses.

(Round your answer to three decimal places.) t = State the rejection region. (If the test is one-tailed, enter NONE for the unused region. Round your answers to three decimal places.) State the conclusion, O Ho is not rejected. There is sufficient evidence to indicate that the average number of completed passes is different for Alex Smith and Joe Flacco. O Ho is not rejected. There is insufficient evidence to indicate that the average number of completed passes is different for Alex Smith and Joe Flacco. O Ho is rejected. There is insufficient evidence to indicate that the average number of completed passes is different for Alex Smith and Joe Flacco O Ho is rejected. There is sufficient evidence to indicate that the average number of completed passes is different for Alex Smith and Joe Flacco. (c) What is the p-value for the test? (Round your answer to three decimal places.) p-value = (d) Use the information provided along with the pooled variance, s2 = 39.4115 to construct a 95% confidence interval for the difference in the average number of completed passes for the two quarterbacks.
