Grocery Store Receipts

APSTAT-LK6PBK

Suppose at a local grocery store, the average customer’s bill is $\$98.22$ with a standard deviation of $\$45.10$.

One day, the manager is surprised to see the next $5$ randomly selected receipts averaged $\$150$. The next day, the manager was even more surprised to see the next $5$ randomly selected receipts were each greater than $\$150$.

Use the probability of each event to find which occurrence is more surprising.

A

$\text{P(5 receipts averaging \$150)} = 0.0051$

$\text{P(5 receipts more than \$150)} = 0.0051$

B

$\text{P(5 receipts averaging \$150)} = 0.0051$

$\text{P(5 receipts more than \$150)} = 0.0000306$

C

$\text{P(5 receipts averaging \$150)} = 0.1251$

$\text{P(5 receipts more than \$150)} = 0.0000306$

D

$\text{P(5 receipts averaging \$150)} = 0.0051$

$\text{P(5 receipts more than \$150)} = 0.0042$
