(1 point) The hypothesis test H0312=3-5 HUM[429535 is to be carried out for population 1 and 2 where 0'1 and 0'2 are not known. A random sample of 45 from population 1 has a mean of 76.7 and a standard deviation of 6.6. A random sample of 33 from population 2 has a standard deviation of 9.5. The test statistic was found to be 16 = 0.77951. What was the mean of the sample from population 2? 562 = 75.27954 (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, SI =17.5 n2 = 29, 562 = 81.6, 32 = 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: 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
