Three landmarks of baseball achievement are Ty Cobb's batting average of 0.420 in 1911, Ted Williams' 0.406 in 1941, and George Brett's 0.390 in 1980. These batting averages cannot be compared directly because the distribution of major league batting averages has changed over the years. The distributions are quite symmetric and, except for outliers such as Cobb, Williams, and Brett, reasonably Normal. While the mean batting average has been held roughly constant by rule changes and the balance between hitting and pitching, the standard deviation has dropped over time. Here are the facts: Decade Mean Std. dev. 1910s 0.266 0.0371 1940s 0.267 0.0326 1970s 0.261 0.0317 According to ESPN, the batting average leaders in 2018 were Mookie Betts of the Boston Red Sox for the American League (AL) and Christian Yelich of the Milwaukee Brewers for the National League (NL). Mookie Betts' batting average is 0.346 and Christian Yelich's batting average is 0.326. AL batting averages had a mean of 0.262 with standard deviation 0.0315, while NL batting averages had a mean of 0.269 with standard deviation 0.0233. Use standard scores to compare the batting averages for Betts and Yelich. Give your answer to two decimal places. Mookie Betts' standard score: Christian Yelich's standard score:

Question 3 (1 point) Researchers wish to carry out a test of the null hypothesis that the mean of a certain population is 430 against the alternative hypothesis that it is less than 430. In their situation, they (somehow) happen to know the population standard deviation. They feel comfortable assuming normality for this population, and carry out a Z test. They draw a sample of 43 individuals from this population, and find a Z test statistic of 0.63. What is the p-value of the test? (Give your numeric response to at least 3 decimal places. Give only your numeric response, and not any extra characters or symbols.)

2. Design a simple MOS current mirror to meet the following constraints: (a) Transistor M2 must operate in the active region for the value of $V_o$ to within 0.2V of ground (b) The output current must be 50 ?A. (c) The output current must change less than 1% for a change in output voltage of 1V. Make $M_1$ and $M_2$ identical. You need to minimize the total device area (W×L) within the given constraints. Assume $k'_n = 100 \frac{\mu A}{V^2}$ and $\lambda L = 0.02 \frac{\mu m}{V}$

Q3: [20 points] (Non-anonymous question)* A cylinder with a piston restrained by a linear spring that applies a pressure of the system that is linearly change with Volume ($P = aV + b$). The cylinder contains 2 kg of carbon dioxide (ideal gas) at 500 kPa, 400°C. It is cooled to 40°C, at which point the pressure is 300 kPa. Calculate the heat transfer (kJ) for the process. Note: $C_p$ = 1.020 kJ/kg.K at the average temperature of the system.
