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 tw…

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 o…

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 compar…

Delta Airlines quotes a flight time of 2 hours, 5 minutes for its flights from Cincinnati to Tampa. Suppose we believe that actual flight times are uniformly distributed between 2 hours and 2 hours, 20 minutes. Answer questions 11-13.

1. (10 ) According to the PayScale data from 2021, the average starting salaries by college major for bachelor's degree are as follows: $70,600 for mechanical engineering, $56,700 for economics, $43,500 for chemistry, and $47,000 for philosophy. In order to estimate the true difference in the average starting salaries by college major in 2022, 60 graduates with these four majors from the class of 2022 were contacted and questioned about their starting salaries. Propose a regression model with dummy variables that could be used to investigate if starting salaries are different by college major and interpret all the coefficients in the model. 0.000
