The marketing manager of a firm that produces laundry products decides to test market a new laundryproduct in each of the firm's two sales regions. He wants to determine whether there will be a differencein mean sales per market per month between the two regions. A random sample of 18 supermarketsfrom Region 1 had mean sales of 81 with a standard deviation of 6.6. A random sample of 12supermarkets from Region 2 had a mean sales of 77.2 with a standard deviation of 5.3. Does the testmarketing reveal a difference in potential mean sales per market in Region 2? Let μ₁ be the mean salesper market in Region 1 and 2 be the mean sales per market in Region 2. Use a significance level ofa = 0.02 for the test. Assume that the population variances are not equal and that the two populationsare normally distributed.Step 1 of 4: State the null and alternative hypotheses for the test.

1) A study compared the weight loss of people on a low-fat diet versus people on a low-carb diet. In a sample of 100 obese people on a low-fat diet the sample mean weight loss as 7.6 pounds with a standard deviation of 3.2 pounds. In another sample of 120 obese people on a low-carb diet the sample mean weight loss was 6.7 pounds with a standard deviation of 3.9 pounds. a) Test the hypothesis, at the 5% level of significance, that there is a difference in the mean weight loss of using the 2 different diets. b) What is the p-value?

Suppose that the quarterly sales levels among health care information systems companies are approximately normally distributed with a mean of 9 million dollars and a standard deviation of 1.4 million dollars. One health care information systems company considers a quarter a "failure" if its sales level that quarter is in the bottom 10% of all quarterly sales levels. Determine the sales level (in millions of dollars) that is the cutoff between quarters that are considered "failures" by that company and quarters that are not. Carry your intermediate computations to at least four decimal places. Round your answer to one decimal place.

Bone mineral density (BMD) is a measure of bone strength. Studies show that BMD declines after age 45. The impact of exercise may increase BMD. A random sample of 59 women between the ages of 41 and 45 with no major health problems were studied. The women were classified into one of two groups based upon their level of exercise activity: walking women and sedentary women. The 39 women who walked regularly had a mean BMD of 5.96 with a standard deviation of 1.22. The 20 women who are sedentary had a mean BMD of 4.41 with a standard deviation of 1.02. Which of the following inference procedures could be used to estimate the difference in the mean BMD for these two types of women
