10. A simple random sample of size n is drawn from a populationthat is known to be normally distributed. The sample mean, x, isdetermined to be 104.3 and the sample standard deviation, s, isdetermined to be 15.9.(a) Construct the 90% confidence interval for the populationmean if the sample size, n, is 15.(b) Construct the 90% confidence interval for the population meanif the sample size, n, is 25. How does increasing the sample sizeaffect the width of the interval?(c) Construct the 95% confidence interval for the populationmean if the sample size, n, is 15. Compare the results tothose obtained in part (a). How does increasing the level ofconfidence affect the confidence interval?(d) Construct the 90% confidence interval for the populationstandard deviation if the sample size, n, is 15.

Note: As per my policy i can answer only three subparts. kindly repost the remaining sub parts.…

4. A very large population has a mean of 180 and a standard deviation of 24. One day a sample of 64 observations is taken. On another day a sample of 100 observations is taken. Which of the following is true? The standard error of the mean will be smaller with 64 observations. It is impossible to determine any of the above given the available information. The standard error of the mean will be larger with 64 observations. The standard error of the mean will be the same with either 64 or 100 observations.

Professor Nord stated that the mean score on the final exam from all the years he has been teaching is a 79%. Colby was in his most recent class, and his class’s mean score on the final exam was 82%. Colby decided to run a hypothesis test to determine if the mean score of his class was significantly greater than the mean score of the population. α = .01. What is the mean score of the population? What is the mean score of the sample? Is this test one-tailed or two-tailed? Why?
