A data set includes distance living from campus for 62 different college students and scores on a stats exam. The paired data were used to obtain the results shown to the right. Is there sufficient evidence to support the claim that there is a linear correlation between distances from campus and scores on a stats exam? Use a significance level of $\alpha = 0.05$. Click here to view a table of critical values for the correlation coefficient. Correlation matrix: Variables Paper Glass Paper 1 0.3848 Glass 0.3848 1 $H_1: \rho \neq$ (Type integers or decimals. Do not round.) Identify the test statistic, $r$. r = (Round to three decimal places as needed.) Identify the critical value(s). (Round to three decimal places as needed.) A. There are two critical values at $r = \pm$ B. There is one critical value at $r =$ State the conclusion. Because the absolute value of the test statistic is the positive critical value, there sufficient evidence to support the claim that there is a linear correlation between distances lived from campus and scores on a stas exam at a significance level of $\alpha = 0.05$.

(2) True or False? No need to explain. (a) Before it's calculated with data, a 95\% confidence interval has a 0.95 probability of capturing the parameter under investigation. After the calculation is made the interval either contains the parameter or doesn't contain it. So we say 95\% of such intervals will contain the parameter and the rest 5\% won't. (b) A confidence interval for $p$ becomes wider (its width increases) when sample size $n$ goes up.

Please calculate the price elasticity of demand (show work). Are there other concerns with our elasticity estimates? What could make this analysis better? What do we expect to happen to Netflix's revenue due to the price increase? What do we expect to happen to Netflix's profit due to the price increase? Given this analysis, why did Netflix stock get hammered after releasing results?

A ball rolls without friction from the top of a 40° inclined plane. Initially, the ball is released from a height $h_1$ = 10 meters; at height $h_2$ = 7 m the inclined plane is covered in ice all the way to the bottom so the ball slides on ice. What is the velocity of the ball as it reaches the end of the inclined plane? Consider the ball is equivalent with a thin wall sphere and g = 9.80 m/s$^2$. Select one: a. 13.1 m/s b. 14.2 m/s c. 17.3 m/s d. 22.2 m/s

Consider the circuit shown in the diagram below. The potential difference across the points a and b is $\Delta V = 120.0 \text{ V}$ and the capacitors have the following values: $C_1 = 15.0 \,\mu\text{F}$, $C_2 = 8.00 \,\mu\text{F}$, $C_3 = 4.00 \,\mu\text{F}$, and $C_4 = 12.0 \,\mu\text{F}$. Initially the capacitors are all uncharged. (a) What is the total charge that has to flow through meter A for the capacitors to go from the initial uncharged state to the final state when they are fully charged? (b) What is the charge on each fully charged capacitor? $Q_1 = \text{ mC}$ $Q_2 = \text{ mC}$ $Q_3 = \text{ mC}$ $Q_4 = \text{ mC}$
