The manager of an automobile dealership is considering a new bonus plan designed to increase sales volume. Currently, the mean sales volume is 14 automobiles per month. The manager wants to conduct a research study to see whether the new bonus plan increases sales volume. To collect data on the plan, a sample of sales personnel will be allowed to sell under the new bonus plan for a one-month period. Blank #1: Should the null hypothesis be µ >=₁ μ <=, or μ = the assumed value? Enter >, <=, or into blank 1. Blank #2: Should the alternative hypothesis be μ>, μ<, or μ the assumed value? Enter>,<, or not equal into blank 2. Blank #3: What value should u be compared to? I.e. what number goes on the right side of what you entered in the first two blanks?

Suppose that you are attempting to determine the necessary sample size required to
compute an interval estimate with a margin of error no larger than 15.5. Further
suppose that the population standard deviation is known to be 50.0 and the desired
confidence level is 99%. Use the table on Ch 08 slide 13 for more precise values of z.
Round your answer to two (2) decimal places (don't round up to the next largest
integer, D2L doesn't have a round-up function so just report the value from the
formula).
