After being rejected for employment, Kim Kelly learns that the Bellevue Credit Company has hired onlythree women among the last 21 new employees. She also learns that the pool of applicants is very large,with an approximately equal number of qualified men as qualified women.Help her address the charge of gender discrimination by finding the probability of getting three or fewerwomen when 21 people are hired, assuming that there is no discrimination based on gender.(Report answer accurate to 8 decimal places).P(at most three) =Because this is a serious claim, we will use a strict cutoff value for unusual events. We will use 0.5% as thecutoff value (1 in 200 chance of happening by chance). With this in mind, does the resulting probabilityreally support such a charge?O no, this does not support a charge of gender discriminationOyes,this supports a charge of gender discrimination

According to the given information,Sample size, n = 21Since, approximately equal number of qualified…

Español According to previous studies, 10% of the U.S. population is left-handed. Not knowing this, a high school student claims that the percentage of left-handed people in the U.S. is 12%. The student is going to take a random sample of 900 people in the U.S. to try to gather evidence to support the claim. Let p be the proportion of left-handed people in the sample. Answer the following. (If necessary, consult a list of formulas.) (a) Find the mean of p. 0.12 (b) Find the standard deviation of p. X 5 (c) Compute an approximation for P(p≤0.12), which is the probability that there will be 12% or fewer left-handed people in the sample. Round your answer to four decimal places. A 27

A researcher wants to determine the percentage of American teenagers who send or receive text messages while doing homework. Which of the following techniques would likely be the MOST efficient way of obtaining an accurate estimate for this percentage? 1. Randomly select teenagers from the list of all teenage students in every state in America and mail surveys to those teens, asking them if they send or receive text messages while doing homework. 2. Send a survey to every teenager in America and ask them if they send or receive text messages while doing homework. 3. Randomly select teenagers from the list of all teenage students in one state and mail surveys to those teens, asking them if they send or receive text messages while doing homework.
