Will give great feedback! :)

1. For the following exercises, perform each of the following steps: a. State the hypotheses and identify the claim. b. Find the critical value(s). C. Compute the test value. d. Make the decision. e. Summarize the results. Walking with a Pedometer An increase in walking has been shown to contribute to a healthier life-style. A Credit Card Debt It has been reported that the average sedentary American takes an average of 5000 steps per credit card debt for college seniors is $3262. The student day (and 65% of Americans are overweight). A group of health-conscious employees of a large health care system senate at a large university feels that their seniors have a volunteered to wear pedometers for a month to record debt much less than this, so it conducts a study of 50 their steps. It was found that a random sample of 40 walkers took an average of 5430 steps per day, and the randomly selected seniors and finds that the average debt population standard deviation is 600 steps. At a = 0.05 is $2995, and the population standard deviation is $1 100. can it be concluded that they walked more than the With a = 0.05, is the student senate correct? mean number of 5000 steps per day?

State whether the null hypothesis should be rejected on Soft Drink Consumption A researcher claims that the the basis of the given P-value. yearly consumption of soft drinks per person is 52 a. P-value = 0.258, a = 0.05, one-tailed test gallons. In a sample of 50 randomly selected people, the b. P-value = 0.0684, a = 0.10, two-tailed test mean of the yearly consumption was 56.3 gallons. The C. P-value = 0.0153, a = 0.01, one-tailed test standard deviation of the population is 3.5 gallons. Find the P-value for the test. On the basis of the P-value, is d. P-value = 0.0232,
