Only 11% of registered voters voted in the last election. Will voter participation change for the upcoming election? Of the 379 randomly selected registered voters surveyed, 34 of them will vote in the upcoming election. What can be concluded at the a = 0.05 level of significance?
Þorgerður, a scientist, used a paired t-test to examine the effectiveness of a drug she is developing. She obtained a p-value =% 3D 0.005 and concluded that the drug was effective (she used a = 0.05). Suppose the drug does not actually work. Which of the following statements is correct? 1. Þorgerður should not reject the null hypothesis because the p-value is too large. 2. Type I error occurred. 3. An error of type II occurred. 4. There was no error

The null and alternate hypotheses are: Ho Hy H2 H₁ H₁ H₂ A random sample of 11 observations from one population revealed a sample mean of 23 and a sample standard deviation of 1.1. A random sample of 4 observations from another population revealed a sample mean of 24 and a sample standard deviation of 1.3. The population standard deviations are unknown but assumed to be equal. At the 0.05 significance level, is there a difference between the population means? Required: a. State the decision rule. (Negative amounts should be indicated by a minus sign.
