Problem 7

In Problems 5–10, use the results of Problems 7–12, respectively, from Section 4.2 to answer the following questions:

(a) What are the estimates of b0 and b1?

(b) Compute the standard error, the point estimate for s.

(c) Determine sb1.

(d) Assuming the residuals are normally distributed, test H0: b1 = 0 versus H1: b1 ≠ 0 at the a = 0.05 level of significance.

Step-by-Step Solution:

Step 1 of 5) The results of Problems 7–12, respectively, from Section 4.2 to answer the following questions: (a) What are the estimates of b0 and b1 (b) Compute the standard error, the point estimate for s. (c) Determine sb1. (d) Assuming the residuals are normally distributed, test H0: b1 = 0 versus H1: b1 ≠ 0 at the a = 0.05 level of significance. To clarify the roles of l and t, revisit Example 1. Here, l = 2 cars per minute, while t = 20 minutes (the length of time between 12:20 p.m. and 12:40 p.m.). Computing Probabilities of a Poisson Process Problem A McDonald’s manager knows that cars arrive at the drive-through at the average rate of two cars per minute between the hours of 12 noon and 1:00 p.m. Determine and interpret the probability of the following events: (a) Exactly six cars arrive between 12 noon and 12:05 p.m. (b) Fewer than six cars arrive between 12 noon and 12:05 p.m. (c) At least six cars arrive between 12 noon and 12:05 p.m.
