the night shift workers in three of the super bo's specialty stores stock about 500 products in about 3 hours. how does the rate compare with the stocking done in the other 97 stores in the chain, which average about 496 products stocked in 3 hours? are the stockers at the specialty stores doing "better than Average" job? here's the info you need size. products stocks standard deviation specialty stores 3. 500. 12.56 all stores. 100. 496. 22.13 using these 7 steps: State the null and research hypotheses. Set the level of risk associated with the null hypothesis. Select the appropriate test statistic. Compute the test statistic value. Determine the critical value(s). Compare the obtained and critical values. Make a decision.
The expected value of the mean is: The mean of the true population means The mean of the standard errors of the mean. The mean of the random sampling errors. The mean of the sampling distribution of the mean.

For the given scenario, determine the type of error that was made if any.(begin by determining the null and alternative hypothesis). A new whitening toothpaste advertises for shades as the mean number of shades the toothpaste whitens your teeth. One user claims that the mean number of shades the toothpaste whitens your teeth is different from four shades. The user conducts a hypothesis test and fails to reject the null hypothesis. Assume that in reality, the mean number of shades the two piece white is your teeth is for shade. Was an error made? If so, what type? A, B, C? A.Yes; type 2 error B.Yes; type 1 error C.No; correct decision
K In a random sample of eleven people, the mean driving distance to work was 22.3 miles and the standard deviation was 4.9 miles. Assume the population is normally distributed and use the t-distribution to find the margin of error and construct a 95% confidence interval for the population mean u. Interpret the results. Identify the margin of error. (Round to one decimal place as needed.) Construct a 95% confidence interval for the population mean. (Round to one decimal place as needed.) Interpret the results. Select the correct choice below and fill in the answer box to complete your choice. (Type an integer or a decimal. Do not round.) OA. It can be said that % of the population has a driving distance to work (in miles) that is between the interval's endpoints. O B. % of all random samples of eleven people from the population will have a mean driving distance to work (in miles) that is between the interval's endpoints. OC. With % confidence, it can be said that most driving distances…
