Question

24) Suppose you want to test the claim that H1> H2. Two samples are randomly selected from each population. The sample statistics are given below. At a level of significance of a = 0.10, when should you reject Ho? (8.1) n2 = 42 ni = 35 x1 = 29.23 $1= 2.9 x2 = 31.78 S2 = 2.8 A) Reject Ho if the standardized test statistic is more than 1.645. B) Reject Ho if the standardized test statistic is more than 1.28. C) Reject Ho if the standardized test statistic is less than -1.645. D) Reject Ho if the standardized test statistic is less than -1.28.

Answer 1

Here we perform t-test, where trtasi na92-2 for a right tailed test. For testing HolizNa vs Hi Nala from We oreject. He atla level of significans if tetas; ntila-2 ( 0 -0) - 7 tapin, 12-2 = toj +2785-2 O = 16+ 26 = SYNN Thus we report to is the standardized test statisties is more than 1.6 (a) of 18-ex
