MO22. A textile fiber manufacturer is investigating a new drapery yarn, which the company claims has a mean thread elongation of12 kilograms with a standard deviation of 0.5 kilograms. The company wishes to test the hypothesis Ho: µ = 12 against H, : H <12, using a random sample of 4 specimens. Find B for the case where the true mean elongation is 11.26 kilograms. Round youranswers to 4 decimal places i.e., 0.0000. Provide all necessary solutions.B = Blank 1Blank 1 Add your answer

To compare the dry braking distances from 30 to 0 miles per hour for two makes of automobiles, a safety engineer conducts braking tests for 35 models of Make A and 35 models of Make B. The mean braking distance for Make A is 41 feet. Assume the population standard deviation is 4.6 feet.The mean braking distance for Make B is 42 feet. Assume the population standard deviation is 4.4 feet. At α=0.10, can the engineer support the claim that the mean braking distances are different for the two makes of automobiles? 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? A.The mean braking distance is different for the two makes of automobiles. This is the correct answer. B.The mean braking distance is the same for the two makes of automobiles. C.The mean braking distance is less for Make A automobiles than Make B automobiles. Your answer is…
69. The sample average unrestrained compressive strength for 45 specimens of a particular type of brick was com- puted to be 3107 psi, and the sample standard deviation was 188. The distribution of unrestrained compressive strength may be somewhat skewed. Does the data strong- ly indicate that the true average unrestrained compres- sive strength is less than the design value of 3200? Test using a = .001.
Someone once dropped a 'mint imperial", a type of sweet, from the top of a multi-story car park and it landed on my grandmother's head. The average speed of a falling mint imperial is 4 m/s and the velocity is a Gaussian distribution with standard deviation 0.25 m/s. If a mint travelling faster than 5 m/s causes injury, what is the chance my grandmother was injured? In fact she was fine, but very annoyed.

A synthetic fiber used in manufacturing carpet has tensile strength that is normally distributed with mean 75.5 psi and standard deviation 3.5 psi. How is the standard deviation of the sample mean changed when the sample size is increased from n = 12 to n = 48? Round all intermediate calculations to four decimal places (e.g. 12.3456) and round the final answer to three decimal places (e.g. 98.768). The standard deviation is reduced by i psi.
