1.Suppose that a random sample of 200 twenty-year-old men is selected from a population and that these men's height and weight are recorded. A regression of weight on height yields

WEIGHT = ( 107.3628) + 4.2552 HEIGHT + error

where Weight is measured in pounds and Height is measured in inches. Provide aninterpretation of the intercept.

2.Suppose that a researcher, using data on class size (CLASS_SIZE) and average test scores estimates the OLS regression

TESTSCORE = 489.17 + ( 5.47) CLASS_SIZE + error

  • Provide the formula for the 99% confidence interval of the slope coefficient and discuss what the confidence interval represent
  • Is zero included in the interval? do you expect a variable to be statistically significant if its confidence interval includes 0?

3.Suppose that you want to estimate the relationship between people's weight (W) and the number of times they eat out in a month (EO):

WEIGHT = 58.84 +1.28* EO + error

Provide aninterpretation of the slope coefficient.
