Like father, like son: In 1906, the statistician Karl Pearson measured the heights of 1078 pairs of fathers and sons. Thefollowing table presents a sample of 6 pairs, with height measured in inches, simulated from the distribution specified byPearson.Son'sheightFather'sheight69.371.466.768.870.771.065.770.972.469.165.466.0Send data to ExcelThe least-squares regression line y = b, +b,x= 50.5230 + 0.2781x and E (x-x)* = 41.2733 are known for this data. Use thecritical value method to test H,:B, = 0 versus H, : B, # 0. Can you conclude that the father's height is useful in predicting theson's height? Use the a = 0.05 level of significance.Part: 0/ 4Part 1 of 4Find the critical value(s). Round the answer to three decimal places. If there is more than one critical value, separatethem with commas.Critical value(s):
