You wish to see if the proportion of Canadians (aged 18 to 29, inclusive) who have coulrophobia, or $p_{coul}$, is higher than the proportion who are afraid of climate change. You will randomly select $n = 1250$ Canadians between the ages of 18 and 29 (inclusive), then determine "how many" are have coulrophobia. (a) (Worth 25%) Select the appropriate statistical hypotheses that you should be testing. A. $H_0 : p_{coul} > 0.33 \quad H_A : p_{coul} \leq 0.33$ B. $H_0 : p_{coul} \leq 0.33 \quad H_A : p_{coul} > 0.33$ C. $H_0 : p_{coul} \geq 0.33 \quad H_A : p_{coul} < 0.33$ D. $H_0 : \hat{p}_{coul} \geq 0.33 \quad H_A : \hat{p}_{coul} < 0.33$ E. $H_0 : \hat{p}_{coul} \leq 0.33 \quad H_A : \hat{p}_{coul} > 0.33$ F. $H_0 : p_{coul} = 0.33 \quad H_A : p_{coul} \neq 0.33$ G. $H_0 : \hat{p}_{coul} > 0.33 \quad H_A : \hat{p}_{coul} \leq 0.33$ H. $H_0 : \hat{p}_{coul} = 0.33 \quad H_A : \hat{p}_{coul} \neq 0.33$ (b) (Worth 25%). You have taken your random sample of $n = 1250$, from which 463 have admitted to having coulrophobia. Compute the test statistic. Test Statistic = 3.038 (use three decimals in your answer) (c) (Worth 30%) Complete the interpretation of the $P$-value by correctly completing the statement below. Enter any computations to five decimals. Assuming that the null hypothesis is is true $\vee$, the probability of equal to $\vee$ will result in stronger evidence against the null hypothesis than the current data $\vee$ is

Problem 1: Equivalent Systems (25%) Saruman has set his Uruk-hai to work building war machines for his assault on Helm's Deep. Realizing that he would rather have them fighting than building, Saruman decides to replace the efforts of the 4 Uruk-hai with one cave troll, each one exerting a force ($F_1, F_2, F_3, F_4$) on the machine. Determine the magnitude, direction, and location of the equivalent force that the cave troll must exert on the arm to achieve an equivalent loading on the machine. Take: $F_1 = 100 lb$ $F_2 = 150 lb$ $F_3 = 260 lb$ $F_4 = 80 lb$ $a = 6 ft$ $b = 2 ft$ $c = 4 ft$ $d = 3 ft$ $\theta = 30^\circ$ Find:
