4. The curve in R² traced out by $\vec{r}(t) = (5 + \sin(10t))\cos(t)\vec{i} + (5 + \sin(10t))\sin(t)\vec{j}$, $0 \le t \le 2\pi$, approximates the perimeter of a sprocket. Draw a picture of the curve. Hint: The motion has the form $\langle R(t)\cos(t), R(t)\sin(t) \rangle$, $0 \le t \le 2\pi$, which is like drawing a circle counter-clockwise while varying the radius with time. Compute the perimeter of the sprocket using numerical integration. Assume the coordinates have units of centimeters (cm).

Estimate the population mean by finding a 99.9% confidence interval given a sample of size 61, with a mean of 72.4 and a standard deviation of 11.3. Preliminary: a. Is it safe to assume that $\pi \le 0.05$ of all subjects in the population? b. Is $n \ge 30$? Confidence Interval: What is the 99.9% confidence interval to estimate the population mean? Enter your answer as an open-interval (i.e., parentheses) accurate to one decimal place. 99.9% C.I. =

A survey was taken of randomly selected Americans, age 65 and older, which found that 405 of 1016 men and 538 of 1054 women suffered from some form of arthritis. a) Are the assumptions and conditions necessary for inference satisfied? Explain, b) Create a 95% confidence interval for the difference in the proportions of senior men and women who have this disease. c) Interpret your interval in this context. d) Does this suggest that arthritis is more likely to afflict women than men? Explain. C. Yes, it was a random sample, less than 10% of the population was sampled, the groups were independent, and there were more than 10 successes and failures in each group D. No, the groups were not independent. b) Let $\hat{p}_1$ be the sample proportion of senior women suffering from some form of arthritis, and let $\hat{p}_2$ be the sample proportion of senior men suffering from some form of arthritis. Create a 95% confidence interval for the difference in the proportions of senior men and women who have this disease, $\hat{p}_1 - \hat{p}_2$ The confidence interval is (Round to three decimal places as needed.)

1. (a) Differentiate the following functions with respect to x, using the appropriate method (e.g. chain rule, product rule, quotient rule, implicit differentiation, logarithmic differentiation, etc.) and express each derivative in its simplest form: (i) $y = \ln[\tan^3(3x - 5x^3)]$ (ii) $x^2y^3 - \frac{1}{x^4} = 4x - 5y$ (iii) $y = \frac{\sqrt{1 + 4x^2}}{\sqrt{1 - 4x^2}}$ (8 marks) (8 marks) (8 marks)
