A sample of 44 cash register receipts revealed these initial purchases:
- a. Arrive at a suggested class interval.
- b. Organize the data into a frequency distribution using a lower limit of $70.

- In the United States, 50% of workers classified as “private industry workers,” those working for non-government businesses, earn an hourly wage of $22.27 or more (SOURCE: National Compensation Survey: Occupational Earnings in the United States, 2010, Bulletin 2753, http://www.stats.bls.gov/ncs/ebs/). Suppose a particular family has a history of working for the government. The family has two parents and four adult-age kids. a. What is the probability that both parents and half of the kids are in the higher earning bracket of government workers? b. What is the probability that only one parent and one child fall into the higher earning bracket of government workers? c. Why is it not possible to group the entire family together as a unit of six individuals and “select two” to calculate the answer to Part b)? Calculate the answer to verify that you do not obtain the same probability by finding it this way.arrow_forwardA school psychologist wants to test the effectiveness of a new method of teaching art.

- The brand manager for a brand of toothpaste must plan a campaign designed to increase brand recognition. He wants to first determine the percentage of adults who have heard of the brand. How many adults must he survey in order to be 95% confident that his estimate is within five percentage points of the true population percentage? Complete parts (a) through (c) below. ..... a) Assume that nothing is known about the percentage of adults who have heard of the brand. (Round up to the nearest integer.) b) Assume that a recent survey suggests that about 86% of adults have heard of the brand. n = (Round up to the nearest integer.) c) Given that the required sample size is relatively small, could he simply survey the adults at the nearest college?

- According to the IRS, individuals filing federal income tax returns prior to March 31 received an average refund of $1,078 in 2018 .

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.
