Which of the following is a correct statement of the null hypothesis? Select one: a. There are no true differences between the groups. Any difference found is due to sampling error. b.

Consider a hypothesis testing situation in which the null hypothesis is p = 0.05 and the alternative is p > 0.5. Data is gathered from a random sample and a test statistic of 2.1 is computed. This means the p-value would have to be: A. less than 0.01. B. between 0.01 and 0.05 C. between 0.05 and 0.10 D. greater than 0.10 E. More information is needed in order to determine the p-value.

Which of the following statements are true? Note that there may be more than one correct answer; select all that are true. In order for the inference procedures for proportions to be valid, the population from which the random sample is drawn must be normally distributed. As the desired margin of error decreases, then the required minimum sample size will increase. When determining the minimum sample size, if the value of p^ is not given, we should use the "worst-case...
