Allegiant Airlines charges a mean base fare of $89. In addition, the airline charges for making a reservation on its website, checking bags, and inflight beverages. These additional charges average $35 per passenger. Suppose a random sample of 80 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 $38. Use z-table.
b. What is the probability the sample mean will be within $10 of the population mean cost per flight (to 4 decimals)?
c. What is the probability the sample mean will be within $5 of the population mean cost per flight (to 4 decimals)?

Write a program that prompts the user to enter five test scores and then print the average test score to the screen. (Assume that the test scores are decimal numbers). Use the following 5 numbers: 10.5 5.5 20.0 10.0 5.5.
I am having trouble understanding where the 5 values are entered in the program.
The program has been provided:
#include <iostream>
#include <iomanip>
using namespace std;
int main()
{
double testScore1;
double testScore2;
double testScore3;
double testScore4;
double testScore5;
cout << "Enter
test score 1: ";

Chebysheff’s Theorem states that the proportion of observations in any population that lie within k standard deviations of the mean is at least 1 – 1 / k² (for k > 1).
According to Chebysheff’s Theorem, there is at least a 0.75 probability that a randomly selected exam taker has a combined score between_______ and_______ .
