K 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 25 Model A washing machines is $212. Assume the population standard deviation is $20. The mean repair cost of 27 Model B washing machines is $228. Assume the population standard deviation is $21. At a=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 Ho and Ha What is the claim? OA. The mean repair costs for Model A and Model B are equal. OB. The mean repair cost for Model A is less than Model B. OC. The mean repair costs for Model A and Model B are different. OD. The mean repair cost for Model A is greater than Model B. Let u₁ be the mean repair cost for Model A and let ₂ be the mean repair cost for Model B. What are Ho and H₂? OA. Ho: H1 H2 Ha H₁242 OD.…
2 134 70 Janet is planning to rent a booth at a festival for a day to sell clothes that she has made. She sells jackets for $202 and skirts for $138. Her past experiences suggests that sales of jackets will have a mean of 7.7 with a standard deviation of 1.7. and sales of skirts will have a mean of 11.7 with a standard deviation of 2.6. The cost of renting the booth for the day is $233. What are the mean and standard deviation of her net income? (Hint: you should first define random variables and use them to express her net income] O A. u= $2937, G = $496.65 O B. u= $3170, o = $38.94 O C. u= $3170, o = $496.65 O D. u= $2937, o = $3170 O E. µ= $2937, a = $38.94 Click to select your answer.

Statistics students believe that the mean score on a first statistics test is 65. The instructor thinks that the mean score is higher. She samples 10 statistics students and obtains the scores: Grades 73.5 63.9 64.3 85.5 62.7 69 88 63.9 65 64.3 Test grades are believed to be normally distributed.Use a significance level of 5%.

Select the correct choice below and, if necessary, fill in the answer box to complete your choice. OA. The mean is 26.9 (Round to one decimal place as needed.) B. The mean cannot be calculated because there is an even number of data entries. C. The mean cannot be calculated because the sample size is too small. D. The mean cannot be calculated because the data are at the nominal level of measurement.
← A study considers if the mean score on a college entrance exam for students in 2005 is any different from the mean score of 499 for students who took the same exam in 1975. Let u represent the mean score for all students who took the exam in 2005. For a random sample of 40,000 students who took the exam in 2005, x = 497 and s= 100. Use this information to complete parts a through c below. a. Find the test statistic. t = -4 (Round to two decimal places as needed.) b. Find the P-value for testing Ho: μ = 499 against H₂: μ#499.

MyOpenMath The mean work week for engineers in a start-up company is believed to be about 65 hours. A newly hired engineer hopes that it's shorter. She asks 10 engineering friends in start-ups for the lengths of their mean work weeks.
