Knee Height x cm 577 474 435 448 552 Overall height y cm 192

Knee Height x (cm) 57.7 47.4 43.5 44.8 55.2

Overall height y (cm) 192.1 153.3 146.4 162.7 169.1 1.

1.What is the predicted “height” when “knee height” is given the value 50 cm and what is the 95% Confidence Interval for this predicted value?

2. Use a significance level of 0.05 to test the claim that in the whole population there is positive slope straight line relation between “height” and “knee height”. Your answer must contain the Null and Alternative Hypothesis, the computed P-Value, and the conclusion for this test
