Read the problem carefully: Consider the weights of 18 month old boys in the U.S. According to published ... than a certain value, your lower boundary will be negative infinity. Use a large negative number like -1000 in these cases. Enter the lower boundary, 10.5, and then press the comma 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 line, it will help you. Figure 6.13 r is not significant between -0.632 and +0.632. r = 0.801 > +0.632.The T critical value can be found by using a t distribution table or by using statistical software. To find the T critical value, you need to specify: A significance level (common choices are 0.01, 0.05, and 0.10) The degrees of freedom. Using these two values, you can determine the T critical value to be compared with the test statistic.T-Test Critical Value: The critical value delimitates the region of acceptance and the region of rejection; that is, values more extreme than the critical value imply that the null must be rejected.
