Two separate samples, each with 16 individuals, receive two different treatments. After treatment, the first sample has SS = 1540 and the second has SS = 1460. If the sample mean difference is 10 points (i.e., M1 - M2 = 10), compute the t-statistic. If it is a decimal number, include the numbers after the decimal point. If it is a decimal number with two or more than two places, leave only two decimal places after the decimal point. Please do not round. The t-statistic is

Suppose IQ scores were obtained for 20 randomly selected sets of siblings. The 20 pairs of measurements yield x=101.22, y=102.45, r=0.916, P-value=0.000, and y=−8.44+1.1x, where x represents the IQ score of the older child. Find the best predicted value of y given that the older child has an IQ of 99? Use a significance level of 0.05.
Use a significance level of a = 9 scores for which x = 3.1 and s = 0.6. Use the traditional method of testing hypotheses. 0.01 to test the claim that u > 2.85. The sample data consist of
