Question 145278This question is from textbook
: I am having trouble trying to figure out how to work this probability problem. Could anyone please help me with these? Thank you so much!
A local retail outlet found that 64 out of a sample 133 customers purchased more than $50 in merchandise in a single trip.
a. Find the probability a randomly selected customer spent more than $50 in a single trip. (Round your answer to 3 decimal places.)
b. Determine whether the probability of error found in #5 is empirical or theoretical probability.
c. Based on these sample values, how many customers out of 2500 would be expected to spend more than $50 in a single trip? Give your answer to the nearest whole number.

A local retail outlet found that 64 out of a sample 133 customers purchased more than $50 in merchandise in a single trip.
a. Find the probability a randomly selected customer spent more than $50 in a single trip. (Round your answer to 3 decimal places.)

We assume 

probability_that_a_customer_spends_more_than_50_dollars+=+64%2F133+=+.481

b. Determine whether the probability of error found in #5 is empirical or theoretical probability.

Empirical

c. Based on these sample values, how many customers out of 2500 would be expected to spend more than $50 in a single trip? Give your answer to the nearest whole number.
