According to the IRS, individuals filing federal income tax returns prior to March 31 received an average refund of $1,078 in 2018 . Consider the population of "last-minute" filers who mail their tax return during the last five days of the income tax period (typically April 10 to April 15). b. For a sample 400 of individuals who filed a tax return between April 10 and 15 , the sample mean refund was $920. Based on prior experience a population standard deviation of a=1,800 may be assumed. What is the p -value (to 4 decimals)? c. Using , can you conclude that the population mean refund for "last minute" filers is less than the population mean refund for early filers? yes or no d.

Many states are carefully considering steps that would help them collect sales taxes on items purchased through the Internet. How many randomly selected sales transactions must be surveyed to determine the percentage that transpired over the Internet?

A job placement agency advertised that last year its clients, on average, had a starting salary of $39,500 . Assuming that average refers to the mean, which of the following claims must be true based on this information? Note: More than one statement could be true. If none of the statements is true, mark the appropriate box. Last year some of their clients had a starting salary of less than $35,000 . Two years ago some of their clients had a starting salary of at least $39,500 . Last year, the number of their clients who had a starting salary of more than $39,500 was equal to the number of their clients who had a starting salary of less than $39,500 . Last year at least one of their clients had a starting salary of exactly $39,500 . Last year all of their clients had a starting salary of at least $39,500 . None of the above statements are true.

How many women must be surveyed in order to be 90% confident that the estimated percentage is in error by no more than one percentage point? Complete parts (a) through (c) below. a. Assume that nothing is known about the percentage to be estimated. n= (Round up to the nearest integer.) b. Assume that a prior study conducted by an organization showed that 83% of women give birth. n= (Round up to the nearest integer.) c. What is wrong with surveying randomly selected adult women? O A. Randomly selecting adult women would result in an overestimate, because some women will give birth to their first child after the survey was conducted. It will be important to survey women who have already given birth. B.
