An article claims the average typing speed for high school students lies between 35.6 and 44.4 words per minute (WPM) at approximate 95% confidence. Their data comes from a sample of 54 students. (Use 1 decimal place.) a. Give the value of x for the sample in the study. b. Give the value of the margin of error for the sample in this study. If you were to create many more confidence intervals from many different random samples, you would expect... c. ..all of the confidence intervals to have centers and widths. d. ..about % of the confidence intervals would not capture the you are trying to estimate.
