Question

A physician wants to test two blood glucose meters to see if there is any difference in measurements. To do this, he measures the glucose in blood samples taken from several randomly selected patients with both meters. Suppose that data were collected for a random sample of 10 patients, where each difference is calculated by subtracting the blood glucose rating from Meter A from the blood glucose reading from Meter B. Assume that the measurements are normally distributed. What is/are the critical value(s) of the t-test statistic for this hypothesis test, where α=0.01? Use a comma and a space to separate answers as needed.
