21) Provide an appropriate response. 21) Assume that adults have IQ scores that are normally distributed with a mean of 100 and a standard deviation of 15 (as on the Wechsler test). Find the probability that a randomly selected adult has an IQ between 90 and 120 (somewhere in the range of normal to bright normal) Maloo and 6=15 POV ,/20-100 1...

6. When or why might you convert raw data to z scores? 7. Briefly define each of the following: a. Distribution of sample means b. Expected value of M c. Standard error of M 8. A sample is selected from a population with a mean of u = 40 and a standard deviation of 8. (Hint: When we take a sample, we expect the mean to be the same as the population mean. Use the equation for standard...

You will be given a series of questions regarding a normal
distribution, you will be asked to either determine the percentage
above or below particular raw scores; or to calculate the raw score
that will correspond to a particular percentage.
You will be asked to calculate either raw scores or
percentages. For each question write out your calculation, the
appropriate Z score, what on the curve you should be shading, the
exact percentage from the normal curve table and the...

Question 5 (25pts) Suppose the athletic director at a university would like to develop a regression model to predict the point differential for games played by the men's basketball team. A point differential is the difference between the final points scored by two competing teams. A positive differential is a win, and a negative differential is a loss. For a random sample of games, the point differential was calculated, along with the number of...
