- Consider the following data set *; | -1|2|3 Yi | 3 |2|1 and the model y = a, + a1¤ Calculate the squared error (SE) for the choice a, = 8 and a1 = -1 Answer:a) Calculate the mean and variance of the following population: 60, 72, 40, 60, 88. Mean: Variance:2. Researchers wanted to study physical activity in children, so they gave 74 randomly chosen children a "FitBit" to record how many steps they took each day. Additionally, the scientists recorded each child's Body Mass Index (BMI) and grade in school. Grade was coded as middle or high school. The results of their analysis are below: Table 1 - Factors Contributing to Daily Steps Taken Intercept BMI Grade_middle Estimate 6,350.2 -137.5 1,302.4 SE 316.1 54.9 588.3 a. Calculate the test statistics for each predictor in the model and determine which are significant (you don't have to write full conclusion for each as long as you indicate which are significant). Given: critical value = 1.99 b. Interpret the estimate of Grade_middle in context. c. Suppose a middle-school student with a BMI of 20 took 6,000 steps in a day. Calculate this student's residual.
