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: ";
        cin >> testScore1;
        cout << endl;
   
        cout << "Enter test score 2: ";
        cin >> testScore2;
        cout << endl;
       
        cout << "Enter test score 3: ";
        cin >> testScore3;
        cout << endl;
       
        cout << "Enter test score 4: ";
        cin >> testScore4;
        cout << endl;
       
        cout << "Enter test score 5: ";
        cin >> testScore5;
        cout << endl;
       
        cout << "Average test score: " << (testScore1+testScore2+testScore3+testScore4+testScore5)/5 << endl;
        cout << endl;

A qualifying exam for a graduate school program has a math section and a verbal section. Students receive a score of 1, 2, or 3 on each section. Define X as a student’s score on the math section and Y as a student’s score on the verbal section. Test scores vary according to the following bivariate probability distribution.

y

1 2 3
1 0.22 0.33 0.05
x 2 0.00 0.08 0.20
3 0.07 0.05 0.00

μXX =   , and μYY =   

σXX =   , and σYY =   

The covariance of X and Y is ________ . The coefficient of correlation is _________ . The variables X and Y_______ independent.

The expected value of X + Y is_______ , and the variance of X + Y is ________________ .

To be accepted to a particular graduate school program, a student must have a combined score of 4 on the qualifying exam.

What is the probability that a randomly selected exam taker qualifies for the program?

0.46

0.33

0.47

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_______ .

True or false for each statement :

1)Without friction or work by an external force, the sum of the potential and kinetic energies of a body is constant.

2)Work is done when the form of energy changes.

3)Work can be done in the absence of motion.

4)Less power is required while slowly lifting a box than while lifting it up quickly.

5)Energy conservation law for a projectile (no friction): Potential energy decrease equals the kinetic energy increase.

6)A source of energy is required to do work.
