While checking receipts at The Hog Cafe, it was determined that the average amount spent on food per table was $21.50 with a standard deviation of $2.22. If we can assume that the amount of money spent was normally distributed, what is the probability that the average of 8 checks is between $20 and $23? 0.9719 0.9438 0.9066 0.8827
