(1 point) Random samples of resting heart rates are taken from two groups. Population 1 exercises regularly, and Population 2 does not. The data from these two samples is given below: Population 1: 61, 64, 63, 68, 65, 69, 71 Population 2: 78, 77, 70, 73,69, 74, 71, 69 x1: 65.8571 31 = 3.579 E2 = 72.625 32 = 22.9l To help see if there is enough evidence to conclude that those who exercise regularly have lower resting heart rates, fill in the information requested. A. The value of the test statistic: 0.0892 B. The degree of freedom of the distribution: For the next part, it is strongly recommended that you use the tables provided by the class C. The approximate range of values for the pvalue: (1 point) Two statistics teachers both believe that each has the smarter class. To put this to the test, they give the same final exam to their students. A summary of the class sizes, class means, and standard deviations is given below: n1 =11, 561: 87, 5] =17.5 n2 = 29, 562 = 81.6, 52 = 18.3 Is there evidence, at an a = 0.15 level of significance, to conclude that there is a difference in the two classes? Carry out an appropriate hypothesis test, filling in the information requested. A. The value of the test statistic: 0.86 B. The degree of freedom for the distribution: E For the next part, it is strongly recommended that you use the tables provided by the class C. The approximate range of values for the pvalue: 0.40
