WebOption A is correct. In statistics, a two-tailed test is a method in which the critical area of a distribution is two-sided and tests whether a sample is greater than or less than a certain range of values. It is used in null-hypothesis testing and testing for statistical significance.. A two-sided significance test rejects the null hypothesis exactly when the claim falls … WebExample. Suppose you computed r = 0.801 using n = 10 data points.df = n – 2 = 10 – 2 = 8. The critical values associated with df = 8 are -0.632 and + 0.632. If r < negative critical value or r > positive critical value, then r is significant.Since r = 0.801 and 0.801 > 0.632, r is significant and the line may be used for prediction. If you view this example on a number …
