Calculate a regression line to predict weight from height for these data from sophomore women.
Height (inches) Weight (pounds)62.0 132.570.5 141.563.5 123.070.5 148.564.0 119.070.5 160.067.5 145.069.5 164.570.0 124.067.0 135.565.5 118.068.0 132.563.5 111.0
Based on your regression, how many more pounds would you predict a woman to weigh than her friend, if she is one inch taller than the friend? In other words, for each inch of height a woman in this study has, how much would you predict her weight increases?
Would you classify these data as time series or cross-sectional and which of the variables are quantitative and which are qualitative?

Use RNG in Excel to generate n = 5 observations from the Normal distribution N(20, 5). Test H0: μ = 20 versus H0: μ ≠ 20 at the α = 0.05 level of significance. Repeat this process 100 times and then count the number of times that you reject H0.
For the following exercise, complete the following: Find the mean, median, and range for each of the two data sets. Find the standard deviation using the rule of thumb for each of the data sets.
