Question
The scores on Ms. Martin's statistics quiz had a mean of 12 and a standard deviation of $3 .$ Ms. Martin wants to transform the scores to have a mean of 75 and a standard deviation of $12 .$ What transformations should she apply to each test score? Explain.
Step 1
The original standard deviation is 3, and Ms. Martin wants it to be 12. The ratio of the desired standard deviation to the original standard deviation is $\frac{12}{3} = 4$. Therefore, she should multiply each score by 4. Show more…
