We want to determine whether the mean starting salary for females in similar entry-level, nonclinical position is different from $29,500. To make this assessment, we randomly select 10 females whose job titles and responsibilities fit our criteria, and we record their starting salaries (in $1000s). The data are: 32 27 31 27 26 26 30 22 25 36 Is the mean starting salary for females significantly different from $29,500?

To earn full credit for this question, use your own sheet of paper to solve the problem, showing all steps of your work. A ping pong ball is drawn at random from an urn consisting of balls numbered 4 through 9. A player wins $1 if the number on the ball is odd and loses $0.5 if the number is even.Let x be the amount of money a player will win/lose when playing this game, where x is negative when the player loses money.(a) Construct the probability distribution table for this game. Round your answers to two decimal places. Outcome x Probability P(x) (b) What is the expected value of player's winnings? Round to the nearest hundreth.(c) Interpret the meaning of the expected value in the context of this problem.
Suppose a car is chosen at random. Let x be the weight of the car (in hundreds of pounds), and let y be the miles per gallon (mpg).
