PLEASE HELP ON ALL. THEY ALL SOMEWHAT RELATE.....
In a recent year, the Better Business Bureau settled 75% of complaints they received. (Source: USA Today, March 2, 2009) You have been hired by the Bureau to investigate complaints this year involving computer stores. You plan to select a random sample of complaints to estimate the proportion of complaints the Bureau is able to settle. Assume the population proportion of complaints settled for the computer stores is the 0.75, as mentioned...

A leading magazine (like Bamon') reported at one time that the average number of weks an ndividual is nemployed is 32.9 weeks. Assume that for the population of all unemployed individuals the population mean length of unemployment is 32.9 weeks and that the population standard deviation is 8.6 weeks. Suppose you would like to select a random sample of 143 unemployed individuals for a follow-up study. Find the probability that a single randomly selected value is between 31.5 and 32.8....
