QUESTION 17 How does the test statistic compare against the critical value under the corresponding tail of the probability distribution? The test statistic is less than or does not exceed the critical value. The test statistic is greater than or exceeds the critical value. The test statistic is equal to the critical value. It cannot be determined at this time if the test statistic is less than, greater than or equal to the critical value. QUESTION 18 According to the spreadsheet output, what is the p-value, expressed as a percentage rounded to two decimal places without insignificant digits?
