Please assist to solve the quetion below: The average wage of data analysts in X Company is $51 per hour with a standard deviation of $21.

PLS. Solve Quickly Applications Problems According to a Sallie Mae survey and credit bureau data, in 2008, college students carried an average of $3173 debt on their credit cards (USA TODAY, April 13, 2009). Suppose that cur- rent credit card debts for all college students have a normal distribution with a mean of $3173 and a standard deviation of $800. Find the probability that credit card debt for a randomly se- lected college student is between $2109 and $3605.

C. Atlantic Video is planning to add the new Marvel movie to their collection, and they predict that this will double their demand (i.e. new arrival rate is 60 customers every hour) and halve the standard deviation of the inter-arrival times. However, they want to keep the average waiting time of customers in line the same as before. Assume that the coefficient of variation for the check-out times does not change. Please answer the following questions. 1) Does the employee need to work twice as fast? If not, calculate the new service rate. 2) What is the average number of customers in the store?
