Multiple Choice

The lecturer decided to estimate the mean mental reading speed for the university students. Randomly, seventy nine students were selected and the speed of their reading was recorded. For this sample, the mean reading speed was 235 words per minute. Suppose that the sample standard deviation was 46 words per minute. Find the margin of error and construct a 95% confidence interval for the mean reading speed for the university students.
