Critical Values Of R Statcrunch. Use the value of r found in Exercise. Reject H 0 if Z.
Z 1-α2 196 Critical region. Critical Values of the Pearson Product-Moment Correlation Coefficient How to use this table df n -2 Level of Significance p for Two-Tailed Test 10 05 02 01 df. Refer to the data in Exercise.
F Enter the numerator and denominator degrees of freedom the direction of the inequality and the probability leave X blank.
Next we take the absolute value of our correlation coefficient. R r is tested using the following t-statistic. Use a comma to separate answers as needed Because the absolute value of the linear correlation coeficient is greater than the positive critical value there s sufficient evidence to conclude that there is a linear correlation between overheaed widths of seals from photographs and the weights of the seals. Select your significance level 1-tailed input your degrees of freedom n - 2 and hit Calculate for R.
