Question

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.

information/data. Enter "DNE" if the question cannot be answered
with the given information/data. HINT: Be sure you look at the
distribution of the data. Answer...
