Find standard error of the mean if rainfall was recorded

Reference no: EM13144838

The daily rainfall experienced by Soaking City has been recorded on 9 randomly selected days throughout the year. This process has been repeated for every possible combination of 9 days in a year. The standard error of the mean has been calculated and is equal to 0.429 inches.

If the rainfall was recorded on 27 (instead of 9) randomly selected days throughout the year, the standard error of the mean would be equal to:

3.429 inches
0.083 inches
0.248 inches
0.048 inches
