Studies show that massage therapy has a variety of health benefits and it is not too expensive. A sample of 13 typical one-hour massage therapy sessions showed an average charge of $52. The population standard deviation for a one-hour session is o = $6.5. (a) What assumptions about the population should we be willing to make if a margin of error is desired? O We should be willing to make the assumption that the population is at least approximately normal. O we should be willing to make the assumption that the population is at least approximately uniform. O We should be willing to make the assumption that the population is at least approximately skewed right. O we should be willing to make the assumption that the population is at least approximately skewed left. O we should be willing to make the assumption that the population is at least approximately bimodal. (b) Using 95% confidence, what is the margin of error in dollars? (Round your answer to the nearest cent.) (c) Using 99% confidence, what is the margin of error in dollars? (Round your answer to the nearest cent.)

The wall street journal reported on several studies that show massage therapy has a variety of health benefits and it is not too expensive. A sample of 10 typical one-hour massage therapy sessions showed an average charge of $59. The sample standard deviation for one hour session is standard deviation of 5.50. A. What assumptions about the population should we be willing to make if a margin of error is desired? We assume the population distribution is normal. We assume normal distribution for the population. B. Using 95% confidence, what is the margin of error? C. Using 99% confident, what is the margin of error?

You may need to use the appropriate appendix table or technology to answer this question. Money reports that the average annual cost of the first year of owning and caring for a large dog in 2017 is $1,448. The Irish Red and White Setter Association of America has requested a study to estimate the annual first-year cost for owners of this breed. A sample of 50 will be used. Based on past studies, the population standard deviation is assumed known with o = $245. 1,902 2,042 1,936 1,817 1,504 1,572 1,532 1,907 1,882 2,153 1,945 1,335 2,006 1,516 1,839 1,739 1,456 1,958 1,934 2,094 1,739 1,434 1,667 1,679 1,736 1,670 1,770 2,052 1,379 1,939 1,854 1,913 2,163 1,737 1,888 1,737 2,230 2,131 1,813 2,118 1,978 2,166 1,482 1,700 1,679 2,060 1,683 1,850 2,232 2,294 (a) What is the margin of error for a 95% confidence interval of the mean cost in dollars of the first year of owning and caring for this breed?

Solar energy is considered by many to be the energy of the future. A recent survey was taken to compare the cost of solar energy to the cost of gas or electric energy. Results of the survey revealed that the distribution of the amount of the monthly utility bill of a three-bedroom house using gas or electric energy had a mean of $117 and a standard deviation of $13. If the distribution can be considered normal: Approximately what percentage of homes will have a monthly utility bill less than $78? Note: Do NOT include the "%" sign Do NOT round any decimals, if applicable
The WAIS is an IQ test. Scores on the WAIS for the 20-34 age group are normally distributed with a mean 110 and a standard deviation of 25. Scores for the 60-64 age group are normally distributed with a mean of 90 and a standard deviation of 25. Find the percent of 20-34-year-olds that have an IQ greater than 120. a. 16% b. z= 0.4 or 40% c. 0.6554 or 65.54% d. 0.3446 or 34.46%

You want to buy a washing machine, and a salesperson tells you that the mean repair costs for Model A and Model B are equal. You research the repair costs. The mean repair cost of 24 Model A washing machines is $209. Assume the population standard deviation is $20. The mean repair cost of 27 Model B washing machines is $215. Assume the population standard deviation is $24. At α=0.01, can you reject the salesperson's claim? Assume the samples are random and independent, and the populations are normally distributed. Complete parts (a) through (e). (a) Identify the claim and state H0 and Ha. What is the claim? A. The mean repair costs for Model A and Model B are equal. B. The mean repair cost for Model A is greater than Model B. C. The mean repair costs for Model A and Model B are different. D. The mean repair cost for Model A is less than Model B. Let μ1 be the mean repair cost for Model A and let μ2 be the mean repair cost for Model B.…
