... selling price. Suppose that one analyst believes that the mean difference between selling asking price and selling price for homes in a particular market area is less than $2,000. To test this using an alpha level equal to 0.05, a random sample of n = 15 homes that have sold recently was selected. T ...

... The “S” in NORMSINV refers to “standard”, as in Standard Normal Distribution. These functions assume you are talking about the cumulative probability from negative infinity up to the value. It can be tricky to get an upper tail value, as you can see in B13 of the spreadsheet shown above. ...
