Hi, I need help with these questions. Thank you.

Answer the questions completely. For each problem: a) Construct a scatterplot of the data (label axes appropriately). b) Find the value of the linear correlation coefficient, r. C) Perform a hypothesis test using a = 0.05 to determine whether there is sufficient evidence to support a claim of linear correlation between the two variables. Use the test indicated (t-test or PPMC table). d) IF there is a significant linear correlation, find the linear regression equation, letting the first variable be the predictor x variable. e) If asked, find the indicated predicted value by using appropriate prediction methods. f) If you need more room, attach your own paper. 1. An experiment was conducted involving 12 subjects to study the effect of the percentage of a certain drug in the bloodstream on the length of time (in seconds) it takes to react to a stimulus. The data are as follows. (Use PPMC table for Hypothesis test.) Find the predicted reaction time for a subject with 5.2% of the drug in his bloodstream. Amount of Drug Reaction time (%) (sec) 1.0 1.5 0.8 2 1.8 2.5 1.4 3 2.1 3.5 1.8 4 2.2 4.5 3.0 5 2.8 5.5 3.0 6 4.1 6.5 4.9 2. Listed below are sizes (in thousands of square feet) and revenue (in millions of dollars) from casinos in Atlantic City. (Use t-test for Hypothesis test.) Predict the revenue for a casino in Atlantic City that is 190 thousand square feet in size. Size (thousand Revenue (millions square feet) of $) 160 189 227 157 140 140 144 127 161 123 147 106 141 101
