Could you help me solve this problem?

Waiting times for an order at Starbucks for all drive-through customers in the US have a uniform distribution from 3 min to 11 min (mean : T min. standard deviation : 2.3 min}. For each scenario below, determine the distribution you would use to answer the question. A random sample of 40 Starbucks drive-through customers will be selected and the average waiting time to receive their orders will be calculated. What distribution would you use to find the approximate probability that the average waiting time to receive their orders for the 40 randomly selected Starbucks drive-through customers is at most 8 minutes? O Uniform (3, 11) O Uniform (7, 2.3) O Normal (7, 2.3) O Normal (7, 0.3637) O t(39)In an attempt to decrease the average waiting time for customers to receive their drive-through orders, some participating Starbucks locations in Fresno, California have added a few touch screen stations for customers to place their orders directly from their vehicles. A random sample of 40 drive-through Starbucks customers who place their order using this new touch screen feature is selected and the waiting time to receive their order is recorded. The resulting sample mean waiting time is 6.5 minutes and the standard deviation is 2.5 minutes. What distribution would you use to assess if the new drive-through ordering feature has significantly decreased the average waiting time to receive an order compared to the 7 minute average wating time reported for all drive-through Starbucks customers in the US?
