1. (15 pts total) Fourteen students participated in a research study on the effect of sleep deprivation in a motor skill task. The students played the game "Operation" either after a full night of sleep or after being kept awake for 36 hours. Each task was measured two weeks apart. Half of the students were randomly assigned to sleep deprivation in the first week and a full night of sleep in the second week, and the other half completed the...

11. Suppose you are interested in estimating the effect of hours spent in an SAT preparation course (hours) on total SAT score (sat). The population is all college-bound high school seniors for a particular year. (i) Suppose you are given a grant to run a controlled experiment. Explain how you would structure the experiment in order to estimate the causal effect of hours on sat. (ii) Consider the more realistic case where students choose how much time to spend in...

**Just need help with one I got wrong** Thank you
Budget Analysis I: A budget is an expression of management's expectations and goals concerning future revenues and costs. To increase their effectiveness, many budgets are flexible, including allowances for the effect of variation in uncontrolled variables. For example, the costs and revenues of many production plants are greatly affected by the number of units produced by the plant during the budget period, and this may be beyond a plant manager's...

1. In the regression equation, the value that gives the amount by which Y changes for one unit in X is called the (a) coefficient of correlation. (b) coefficient of determination. (c) slope. (d) intercept. 2. For any two categorical variables, X and Y, the best way to determine if they are related is to (a) calculate the correlation between X and Y. (b) draw a scatterplot of the X and Y values. (c) make a two-way table of the...
