On a test at Microsoft, which has a mean of 500 and a standard deviation of 100, only the top 2% of the test takers will get an interview with Bill Gates. What score or better will they have to earn on this test to get the interview? Please show the work. I can use excel so if you could explain how to do it in there, that would be even better! :)

So If I had a mean of 100, a standard deviation of 10 - Find the z-score based upon an observation of 110. Also which side of the "curve" would the observed value of 110 reside based upon the given mean and standard deviation? Explain.

The standard IQ test is designed so that the mean is 100 and the standard deviation is 15 for the population of all adults. We wish to find the sample size necessary to estimate the mean IQ score of physics students. Suppose we want to be 90% confident that our sample mean is within 2 IQ points of the true mean. Assume then that σ= 15 and determine the required sample size. I think I messed up my calculations, please...

Can someone please explain how to calculate the z-score?
I was using the formula z=(x-mean)/standard deviation, but it keeps
getting marked incorrect.
