Allegiant airlines charges a mean base fare of $86. in addition, the airline charges for making a reservation on its website, checking bags, and inflight beverages. these additional charges average $38 per passenger. suppose a random sample of 70 passengers is taken to determine the total cost of their flight on allegiant airlines. the population standard deviation of total flight cost is known to be $35. use z-table. a. what is the population mean cost per flight?

Answer 1

The population mean cost per flight for Allegiant airlines is $124.

Step-by-step explanation:

In this scenario, we are given the mean base fare charged by Allegiant airlines, which is $86. Additionally, the average of the additional charges for making a reservation, checking bags, and inflight beverages is $38 per passenger. We are told that a random sample of 70 passengers is taken to determine the total cost of their flight. The population standard deviation of total flight cost is known to be $35.

To find the population mean cost per flight, we need to sum up the base fare and the average additional charges. So, the population mean cost per flight can be calculated as:

Population mean cost per flight = Base fare + Average additional charges

Population mean cost per flight = $86 + $38 = $124

Therefore, the population mean cost per flight is $124.
