9. TI Calculator Graded Problem Set

You are conducting a study testing whether a child’s age is a good predictor of his or her height. You have collected the following data from a random sample of seven children:

Age (months) Height (cm)

34 77

5 0 95

63 109

59 99

53 101

44 106

40 94

Perform a regression of height (dependent variable) on age (independent variable).

What is the Y-intercept of the regression line?

43.73

52.81

60.46

24.73

59.70

What is the slope (beta) of the regression line?

1.16

1.27

0.75

1.61

1.52

The regression model predicts that a 4-year-old child (48 months) would be approximately tall.

Problem 2 (20 pts). Hypothesis testing - Imagine a study designed to test whether daughters resemble their fathers. In each trial of the study, a participant examines a photo of one girl and photos of two adult men, one of whom is girl's father. The participant must guess is the father. If there is no daughter-father resemblance, then the probability that the participant guesses correctly is only 1/2. Possible-meaningful hypotheses are: Ho: Participants pick the father correctly half the time...
