The data set contains several variables, including: colGPA: College GPA skipped: average number of lectures missed per week alcohol: average number of days per week drink alcohol. Based on the data, we run three regression models as follows: 1. Model 1 (i.e., model.1):  

Which muscle type is described as uninucleate, fusiform shape, has the slowest contraction speed, and contains actin and myosin that are not arranged into sarcomeres?

Advanced Bonus Question 1 (5 points) When we do hypothesis tests, First, we need to define our null hypothesis. Second, we need to assume the distribution of test statistics under the null hypothesis. For example, the z-test assumes normal distributions under the null hypothesis the t-test assumes t-distributions under the null hypothesis the F-test assumes F-distribution under the null hypothesis Third, we draw the null distribution and decide on critical value (CV) and rejection region based on the statistical significance level. Fourth, we get test statistics from observed sample data. Fifth, we need to compare test statistics with critical value (CV)  to decide whether to accept or reject the null hypothesis, or we need to compare p-value with statistical significance to decide whether to accept or reject the null hypothesis.  In particular,  when we know that (1) a random variable X in a population follows a normal distribution, (2) mean of X in the population  (3) randomly selected sample data for X from the population that follows a normal distribution. (4) sample mean and variance of X in the sample data.  However, we do not know ______________________ In this case, we can apply t-test for hypothesis tests.

40) After getting an A on your economics exam, you decide to go to your favorite Mexican restaurant to celebrate. You are having trouble deciding whether to order the chipotle chicken chimichanga or the cilantro seafood enchiladas. Use the rule of equal marginal utility per dollar to determine which one to purchase: (a) the chimichanga for $8 which gives you 120 units of utility, or (b) the enchiladas for $15 which gives you 195 units of utility? Assume your budget is large enough to purchase either item.
