A recent poll indicated that 28.58% of Canadians planned on attending a Remembrance Day Ceremony this year. A statistician randomly selected n = 580 Canadians aged 18 or over, and asked each one if he/she plans on attending a Remembrance Day Ceremony this year. (a) Complete the statement below. Enter your answer using all the decimals you can. The distribution of $\hat{p}$ is approximately Normal with a mean $\mu_{\hat{p}} = $ and a standard deviation $\sigma_{\hat{p}} = $ (b) What is the probability that the proportion/percentage of the n = 580 Canadians sampled who plan on attending a Remembrance Day Ceremony is between 26% and 33%? Enter your answer using all the decimals you can. (c) Find the probability that the value of the sample proportion/percentage will be at most 23%. $P(\hat{p} \le 0.23) = $ Enter your answer using all the decimals you can.

Supplemental Question 4: A 750-g rectangular block moves across the top of a smooth cylindrical surface with an initial velocity of $V_0$ m/s. The radius of curvature of the cylinder is 1.6 m, as shown in the figure, and the block begins to lose contact with the surface at the position where $\theta = 30^\circ$. Calculate the value of $V_0$ required to satisfy the stated condition.

Consider the hypotheses shown below. Given that $x = 116$, $s = 26$, $n = 49$, $? = 0.10$, complete parts a through c below. $H_0: ? = 128$ $H_A: ? ? 128$ a. State the decision rule in terms of the critical value(s) of the test statistic. Reject the null hypothesis if the calculated value of the test statistic, $z$, is greater than the critical value(s). Otherwise, do not reject the null hypothesis. (Round to two decimal places as needed. Use a comma to separate answers as needed.) b. State the calculated value of the test statistic. The test statistic is (Round to two decimal places as needed.) c. State the conclusion. Because the test statistic is less than the critical value, do not reject the null hypothesis and conclude the population mean is equal to 128.
