Problem 1 (5pts) An overflow valve, shown in sketch below, has a piston diameter of 15 mm and a slit length of 5 mm. The spring has mean coil diameter D = 10 mm and wire diameter d = 2 mm. The valve should open at 1 bar pressure and be totally open at 3 bar pressure when the spring is fully compressed. The shear modulus for the spring material G = 80 GPa. Spring ends are squared and ground. Calculate: //// 15 1.1. The number of active coils. 1.2. The free length of spring. 1.3. The pitch of the spring. 1.4. Determine the maximum shear stress for this geometry.

A study at Yellowstone National Park found that the percent of the population of grizzly bears that are female is 54%. A statistician feels that this number has increased in recent years and decides to test this claim. She randomly collects a sample of 50 bears throughout the park and finds that 32 of them are female. Does the data back up the statistician's claim? Use $\alpha = .01$. (20 points) 1. Formulate the hypotheses: $H_o$: $H_a$: State the significance level: $\alpha = $ 2. Model the sampling distribution of the proportion: n= x = $\hat{p} = $ Test statistic = Z = (please label on the curve) $\mu_{\hat{p}} = $ $\sigma_{\hat{p}} = $ 3. P-value = (please label on the curve) 4. Decision Rule: Reject $H_o$ if < 5. Sate your conclusion: Since the p-value is than $\alpha$, we $H_o$. We can conclude that:
