Editors preparing a report on the economy are trying to estimate the percentage of businesses that plan to hire additional employees in the next 60 days. They are willing to accept a margin of error of 77% but want 99% confidence. How many randomly selected employers will they need to contact?
n=
Homework Answers
Ans:
Margin of error=7% or 0.07
z for 99% confidence level=2.58
Sample size required,n=2.58^2*0.5*(1-0.5)/0.07^2
n=340

A cruise company would like to estimate the average beer consumption to plan its beer inventory levels on future seven-day cruises. (The ship certainly doesn't want to run out of beer in the middle of the ocean!) The average beer consumption over 15 randomly selected seven-day cruises was 81,784 bottles with a sample standard deviation of 4,549 bottles. A. Construct a 99% confidence interval to estimate the average beer consumption per cruise The 99% confidence interval to estimate the average...
