Question

Quizplus · Accepted Answer

Michelle's prediction is a specific value, the average slowing of reading times by 6.9 milliseconds, which is a point estimate. Interval estimates provide a range of possible values, standard deviation measures the variability of the data, and sigma score is not a commonly used term in statistics.
