Take a look at Table 11.1. You are interested in testing H0 : σ² ≥ 10 against the alternative Ha : σ² < 10. You observe a random sample of 20 observations and use a significance level of 1%. When do you reject the null hypothesis? When χ² > 36.191. When χ² > 37.566. When χ² < 36.191. When χ² < 7.633.

A study was conducted to test the effectiveness of a software patch in reducing system failures over a six-month period. Results for randomly selected installations are shown below. The "before" value is matched to an "after" value, and the differences are calculated. The differences have a normal distribution. Test at the 1% significance level. Installation Before After Step 1: State the null and alternative hypotheses: Right, left or two tailed Step 2: Alpha level = Step 3: What is the test statistic? Step 4: What is the p value Step 5: Reject or do not reject the null hypothesis and explain in words

Conduct a test at the α = 0.10 level of significance by determining (a) the null and alternative hypotheses, (b) the test statistic, and (c) the P-value. Assume the samples were obtained independently from a large population using simple random sampling. Test whether p1 > p2. The sample data are x1 = 122, n1 = 251, x2 = 142, and n2 = 312. Choose the correct null and alternative hypotheses below: H0: p1 = 0 versus H1: p1 ≠ 0 H0: p1 = p2 versus H1: p1 ≠ p2 H0: p1 = p2 versus H1: p1 < p2 H0: p1 = p2 versus H1: p1 > p2
