5. A manufacturer claims that the mean tensile strength of thread A exceeds the average tensile strength of thread B. To test his claim, 16 sample pieces of each type of thread are tested under similar conditions. Type A thread had a sample average tensile strength of 185 kilograms with a standard deviation of 6 kilograms, while type B thread had a sample average tensile strength of 178 kilograms with a standard of 9 kilograms. Assume that both populations are...

The strength coefficient (K) and the work hardening exponent (n) for a stainless steel were determined during the analysis of the data from a tensile test using a standard tensile specimen. The flow curve parameters for the stainless steel are K= 1250 MPa and n = 0.4. A compression test is performed on a specimen of the stainless steel. If the starting height and diameter of the specimen are 80 mm and 18 mm, respectively and the final height of...

1. Random samples of size 15 are repeatedly drawn from a distribution that can be approximated by a normal distribution with a mean of 65 and a standard deviation of 17. Since the values in the sample are random variables, the mean associated to those samples, ?̅, is also a random variable. a. What is the expected mean of the distribution of ?̅? b. What is the expected standard deviation of the distribution of ?̅? Hi Chegg Answerer, could you,...

A study using two random samples of 35 people found the average amount of time spent on leisure activities for a the group in their 20s was 39.6 hours. The population standard deviation is 6.3 hours. The average time for a group in their 30s was 35.4 hours, and the population standard deviation was 5.8 hours. At LaTeX: \alphaα=0.05, is there a difference in the average times? (Let 1 = group in 20s and 2 = group in 30s) The...

The ideal (daytime) noise-level for hospitals is 45 decibels with a standard deviation of 10 db; which is to say, this may not be true. A simple random sample of 70 hospitals at a moment during the day gives a mean noise level of 47 db. Assume that the standard deviation of noise level for all hospitals is really 10 db. All answers to two places after the decimal.(e) Assuming our sample of hospitals is among the most typical half...
