Calculate the test statistic and determine the P-value. (Round your test statistic to two decimal places and your P-value to four decimal places.) t = P-value = (b) Using σ = 150, b) what is the type II error probability of the test used in (a) when true average repair time is actually 300 min? That is, what is β(300)? (Round your answer to two decimal places.) β(300) =

The manufacturer of a new model car (Camry) claims that a typical car gets 26 miles per gallon. A consumer advocacy group is skeptical of this claim and thinks that the mean gas mileage, of all Camrys may be less than 26 mpg. The group plans to perform the hypothesis test at sigma = 0.05, using a sample of 30 Camrys.H0: u=26 mpg Ha: u<26 mpg. Find the probability of making a Type II error if the true mean mpg of all Camrys is 25.8 mpg. Assume that gas mileages of Camrys are normally distributed with a standard deviation of 1.4 mpg.
In a random sample of 75 eighth grade students scores on a national mathematics assessment test has a mean score of 266. The test result prompts a state school administration to declare that the mean score for the stated eighth graders on this exam is more than 260. Assume the population standard deviation is 34. At a=0.09, is there enough evidence to support the administrations claim? Write the claim mathematically and identify Ho and Ha Find the standardized test statistic z, and its corresponding area
The quality control department has collected data on defective productsproduced over a 24-hour time span. Using a random sample of 800 products, theydiscover that the average number of defects is 254, while the sample standard deviationis 30. The department wants to conduct a test of whether the average number ofdefective product is 250 or not.Which of the following statements is true?I. The null hypothesis can be rejected with 68% confidence.II. The null hypothesis can be rejected with 95% confidence.III. The null hypothesis can be rejected with 99.7% confidence.A) I onlyB) II onlyC) III onlyD) All three statements
Consider statistics on plasma levels for a random sample of nine 17 year old males and six 17 year old females. Test if two means different, µ1≠µ2, at 5%. Hint. Use a degrees of freedom of 5. Male Female Sample size 9 6 Sample mean 3.259 1.413 Sample standard deviation 0.4 0.22 a. At the 0.05 level of significance, the data provide sufficient evidence to conclude that average male plasma amount is not different from the average female plasma amount. b. At the 0.05 level of significance, the data provide insufficient evidence to conclude that average female plasma amount is equal to the average male plasma amount. c. At the 0.05 level of significance, the data provide sufficient evidence to conclude that average male plasma amount is different from the average female plasma amount. d. At the 0.05 level of significance, the data provide insufficient evidence to conclude that average male plasma amount is different from the average female plasma amount.
