9. (20 pts) A fishing line manufacturer claims that his new X-25 series has an average tensile strength (H) of 25 psi following a normal distribution. To verify his claim, a sample of 25 specimens was tested and yielded the following results: 32, 19, 27, 24, 28, 29, 38, 30, 25, 33, 18, 25, 37,28, 20, 32, 23,21, 25, 19, 23,27, 32, 26,30 this fishing line not meeting the specifications?

Help with question 10 please and thank you.
Question 10 14 pts Suppose X is a random variable with mean 100 and standard deviation 15. Suppose that we select random samples of size n = 81 to construct a sampling distribution of means. Then which of the following is NOT true? O The standard deviation of the sampling distribution is 15/9 The mean of the sampling distribution is 100 Given enough samples, the shape of the sampling distribution will be...

sing R please, 1. Generate 5,000 iid samples from the standard normal distribution; compute the mean of these random samples. Repeat this process 100 times so you would have stored 100 sample averages. Plot the sample averages using hist() and lines(density() in R. What do you observe? 2.
