The probability is 0.7 that a person shopping at a certain store spend less than \$20.00. For groups size of 22, find the mean number who spend less than \$20.00

Do they tell you the most probable amount spent? There are an infinite number of combinations of mean amount spent and standard deviation that can result in a 70% probability of spending \$20 or less. You need one additional bit of information to answer the question.

Solve the problem: The probability is 0.7 that a person shopping at a certain store "WILL" spend less than \$20.00. For groups size of 22, find the mean number who spend less than \$20.00
