A study of solar energy generation along highways had researchers compare the mean monthly amount of solar energy generated by east-west- and north-south-oriented solar panels using a matched-pairs experiment. However, a small sample of only five months was used for the analysis. How many more months would need to be selected to estimate the difference in means to within 30 kilowatt-hours with a 99% confidence interval? Use the information provided in the data table to find an estimate of the standard error required to carry out the calculation. E Click the icon to view the data table.
