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.

Consider the following scenario. You conduct a RCBD ANOVA test and calculate a test statistic of 3.48 for your primary research question. You had 6 different treatment groups, and 5 levels of your blocking variable. What would be the most correct conclusion to come to using a significance level of 5%? O A. Reject the null hypothesis since the p value is greater than 0.05 and conclude that at least one of the treatment group means are different to the...

Which of the following statements is true? I. If the p-value is 0.01, we reject H0 for any alpha level less than 0.01. II. If we use an alpha level of 0.05, then a p-value of 0.005 is not statistically significant. III. If we use an alpha level of 0.05, then we fail to reject the null hypothesis if the p-value is 0.1. Group of answer choices I only II only III only I and III II and III

The U.S. Center for Disease Control reports that the mean life expectancy was 47.6 years for whites born in 1900 and 33.0 years for nonwhites. Suppose that you randomly survey death records for people born in 1900 in a certain county. Of the 124 whites, the mean life span was 45.3 years with a standard deviation of 12.7 years. Of the 82 nonwhites, the mean life span was 34.1 years with a standard deviation of 15.6 years. Conduct a hypothesis...
