A university surveyed recent graduates of the English department about their starting salaries. Four hundred graduates returned the survey. The average salary was $25,000. Assume for purposes of this problem that the population standard deviation is known, and it is $2,500. A 95% confidence interval is constructed. What does the confidence interval mean? Group of answer choices There is a 95% probability that the population parameter will not lie within the interval constructed using the sample's data. The population mean...

You have been asked to build a confidence interval of the population mean starting salary for registered nurses in the United Stats. You already know that the population standard deviation for starting salaries is $7000 per year, and you want a margin of error no greater than plus or minus $1000. What is the minimum sample size that you should gather. If you want to have a level confidence of 95$%?

Annual starting salaries for college graduates with degrees in business administration are generally expected to be between $30,000 and $45,000. Assume that a 95% confidence interval estimate of the population mean annual starting salary is desired. a. What is the planning value for the population standard deviation? How large a sample should be taken if the desired margin of error is b.$500? c.$200? d.$100? e.Would you recommend trying to obtain the $100 margin of error? Explain.

An experiment is conducted to compare the starting salaries of male and female college graduates who find jobs. Pairs are formed by choosing a male and a female with the same major and similar grade point averages. Suppose a random sample of 10 pairs is formed in this manner and the starting annual salary of each person is recorded. The differences within the pairs are obtained by subtracting the female salary from the male salary. The following results are obtained:...
