The results are shown in the table. Assume that the two samples are independent simple random samples selected from normally distributed populations, and do not assume that the population standard deviations are equal. Compiete parts (a) and (b) below Use a 0.01 H level for both parts The test statistic, t, is(Round to two decimal places as needed) )More in the MacBook Dll Do 2.

Explanation / Answer

Two-Sample T-Test and CI

Sample   N    Mean StDev SE Mean
1       11 97.770 0.870     0.26
2       59 97.350 0.690    0.090

Difference = (1) - (2)
Estimate for difference: 0.420
99% CI for difference: (-0.427, 1.267)
T-Test of difference = 0 (vs ): T-Value = 1.51 P-Value = 0.156 DF = 12

Test statistics = 1.51
