one-of-your-distributors-reports-an-average-of-150-sales-per-day-you-suspect-that-this-average-is-not-accurate-so-you-randomly-select-35-days-and-determine-the-number-of-sales-each-day-the-s-01855

One of your distributors reports an average of 150 sales per day. You suspect that this average is not accurate, so you randomly select 35 days and determine the number of sales each day. The sample mean is 143 daily sales with a standard deviation of 15 sales. At α=0.10 is there enough evidence to doubt the distributor’s reported average? a. Identify the claim. Then state the null and alternative hypotheses. b. Identify the level of significance. c. Find the standardized test statistic z. d. Find the P-value. e. Decide whether to reject the null hypothesis. f. Interpret the decision in the context of the original claim.

A group of randomly selected 50 sales representatives from a company this year had an average sales of $107.5 million this year. Assume the standard deviation of sales is stable at $20.5 million. Use your data to find a range of likely values for average sales for all representative in the entire company The average sales for the entire company last year was reported to be $100 million. According to your results from the previous problem, do you think the average sales have changed this year? Why or why not? If so, how has it changed? (Hint: Think about what your range of likely values is for average sales.)

00:03 And so there's no numbers in here.
00:05 So let's just talk about what the table that's called a contingency table means.
00:11 It means we have n items.
00:15 And in this case, it looks like it would be 150.
00:18 They do give us that number that they sampled.
00:23 And then it looks like they're looking for what happens before and after.
00:28 So before and after some what? we're not sure.
00:31 Maybe after some before a new boss, after a new boss, or before a move, after a move...
