Consider the data below of inches of rainfall per month for a region in the Northwestern United States: Plains

April 25.3

May 17.1

June 18.9

July 17.3

August 16.8

Using SPSS, find a 90% confidence interval for the average rainfall per month in this region. Be sure to set the test value to 0 if you have no specific value in mind and SPSS will find the confidence interval for how far off your mean is from 0. Using the formula from the Week 7 notes and hand calculations, how many months’ worth of data would we need to look at to be sure that our margin of error is less than 3 ??.?

I answered this question, apparently incorrect. My professor responded with "There is no SPSS output here; be sure to use the one-sample t-test walkthrough and to state what your conclusion is from the output. The formula for minimum sample size from the week 7 notes is n >= (t* s / M) ^ 2, so try to use that to find the number of months needed" Can someone please answer this with the above formula so I can get an...
