A) One of your team's goals is to figure out how to significantly increase the number of online sales that are 150 dollars or more.

What is the probability that a single randomly selected online transaction is greater than 150 dollars? Enter the probability below IF it can be computed. Enter "DNE" if the question cannot be answered with the given information/data. HINT: Be sure you look at the distribution of the data.

B) Your team selects a simple random sample of 53 online transactions from the current week (and continues to assume that the data set represents the population well).

What is the probability that the random sample has a mean that is greater than 150 dollars? Enter the probability below IF it can be computed. Enter "DNE" if the question cannot be answered with the given information/data.
