6. find the mean and standard deviation of the drive variable by copying that variable into the week 1 spreadsheet. use the week 4 spreadsheet to determine the percentage of data points from that data set that we would expect to be less than 25. to find the actual percentage in the dataset, sort the drive variable and count how many of the data points are less than 25 out of the total 35 data points. that is the actual percentage. how does this compare with your prediction?
