A report states that the mean yearly salary offer for students graduating with accounting degrees in 2012 was $49,007. Suppose that a random sample of 60 accounting graduates at a large university who received job offers

resulted in a mean offer of $49,800 and a standard deviation of $3,100. What is the observed significance level?

The correct answer is 0.261, but I'm not sure how to get there.

The significance level of difference in fhe two means is indeed 0.26.

Step-by-step explanation:

To obtain the significance level, just standardize the mean in 2012 with the new mean and standard deviation.

The standardized score (z) is the value (x) minus the mean (xbar) then divided by the standard deviation (σ)

z = (x - xbar)/σ = (49007 - 49800)/3100 = - 0.26

Therefore, the significance level of difference is indeed 0.26.

answer: input the dimensions of the room to be painted. click the button to calculate the amount of paint and man-hours needed for this job.

interior paint coverage depends on the brand of paint used. the coverage amount is listed on the label of the paint can. use this to adjust the values in the paint coverage section below. paint usually is applied at 350 to 400 square feet per gallon (primer at 200 to 300 square feet per gallon).
