Wall Street Journal reported on several studies that show massage therapy has a variety of healthbenefits and it is not too expensive. A sample of 10 typical one-hour massage therapy sessionsshowed an average charge of $59. The population standard deviation for a one-hour session iso = $5.45.a. What assumptions about the population should we be willing to make if a margin of error is desired?The population is at least approximately normal is requiredb. Using 95% confidence, what is the margin of error (to 2 decimals)?c. Using 99% confidence, what is the margin of error (to 2 decimals)?

Given n=Sample size=10 X=Mean=59 σ=Standard deviation=5.45

You measure 27dogs' weights, and find they have a mean weight of 63 ounces. Assume the population standard deviation is 6.1 ounces. Based on this, what is the maximal margin of error associated with a 95% confidence interval for the true population mean dog weight.
You measure 38 textbooks' weights, and find they have a mean weight of 58 ounces. Assume the population standard deviation is 3.9 ounces. Based on this, construct a 90% confidence interval for the true population mean textbook weight .
In a recent sample of 89 used cars sales costs, the sample mean was $6,225 with a standard deviation of $3,151. Assume the underlying distribution is approximately normal.

Choose the appropriate statistical test. When computing, be sure to round each answer as indicated. A dentist wonders if depression affects ratings of tooth pain. In the general population, using a scale of 1-10 with higher values indicating more pain, the average pain rating for patients with toothaches is 6.8. A sample of 30 patients that show high levels of depression have an average pain rating of 7.1 (variance 0.8). What should the dentist determine? 1. Calculate the estimated standard error. (round to 3 decimals). [st.error] 2. What is thet-obtained? (round to 3 decimals). 3. What is the t-cv? (exact value) 4. What is your conclusion? Only type "Reject" or Retain"
Sam is the manager of a used clothing store. He wants to estimate the average amount a customer spends per visit. A random sample of 70 customers’ receipts gave a mean of = $7.10 with a standard deviation s = $2.30. Find a 99% confidence interval for the average amount spent by all customers. Interpret your findings.
