Provide an appropriate response. Suppose that you perform a two-proportion z-test and reject the null hypothesis that there is no difference in the two proportions. If that conclusion is actually wrong, which type of error did you commit? No error was committed. The conclusion is correct. Type 1 Error Type II Error

Suppose that the null hypothesis of an experiment is and the alternative is . Running the experiment gives the test mean and with a standard error that was estimated from the sample. Under what circumstances would you reject the null hypothesis? Select one: a. lies within the 95% percent confidence interval around , based on the normal distribution and . b. does not lie within the 95% percent confidence interval around , based on the t-distribution and with degrees of...
