Inverse Normal Distribution
The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.
Mean, Median, Mode
It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.
Z-Scores
A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.

![(g) Find a 95% confidence interval for the slope term of the model, B1.
Lower Bound =
67.571
(use three decimals in your answer)
Upper Bound =
76.314
(use three decimals in your answer)
(h) Choose the correct interpretation of the meaning of your confidence interval for B1, in the the context of the data.
A. There is a statistical relationship between the cost of flying a commercial flight using Boeing 737s and the number of passengers.
B. As the cost of flying a commercial flight using Boeing 737s increases by 1 unit, the number of passengers increases by an amount that is somewhere between the lower and upper bounds found in (g).
C. As the number of passengers increases by 1, the cost of flying a commercial flight using Boeing 737s increases by an amount that is somewhere between the lower and upper bounds found in (g).
D. As the cost of flying a commercial flight using Boeing 737s increases by 1 unit, the number of passengers will increase, on average, by an amount that is somewhere between the lower and upper bounds found in (g).
E. As the number of passengers increases by 1, the cost of flying a commercial flight using Boeing 737s will increase, on average, by an amount that is between the lower and upper bounds found in (g).
F. There is no statistical relationship between the cost of flying a commercial flight using Boeing 737s and the number of passengers.
(1) With 95% confidence, find the average cost of flying a commercial flight using Boeing 737s when the number of passengers is 70.
