population has a mean 75 and standard deviation 12. a. A random sample of size 121 are taken. Find the mean and the standard deviation of the sample mean. b. How would the answer to Problem (a) change if the size if the sample were 400 instead of 121.

PLS. Solve Quickly Applications Problems According to a Sallie Mae survey and credit bureau data, in 2008, college students carried an average of $3173 debt on their credit cards (USA TODAY, April 13, 2009). Suppose that cur- rent credit card debts for all college students have a normal distribution with a mean of $3173 and a standard deviation of $800. Find the probability that credit card debt for a randomly se- lected college student is between $2109 and $3605.

Use the chart below to answer questions 1-6 about the ACT's. The ACT is a standardized test used by college admissions offices as a factor in whether an applicant is or is not admitted to their college. Since so many students take this test each year, the distribution of results are typically approximately normal. The table below shows the mean and standard deviation for each section of within the ACT for all test takers in the years 2015, 2016, and 2017.
