Relying on STATA provided $t$ Distribution probabilities to answer this question. We estimated the model $y = \beta_0 + \beta_1x_1 + \beta_2x_2 + \beta_3x_3 + u$ using a data set with 103 observations. We have $\hat{\beta_1} = -1.41$ and $se(\hat{\beta_1}) = 0.75$. What is the P-value if we test $H_0: \beta_1 = -1$ against $H_a: \beta_1 \neq -1$?

A yeast culture weighing 2 grams is removed from a refrigerator unit and is expected to grow at the rate of $W'(t) = 0.1t^{0.2}$ grams per hour at a higher controlled temperature. How much will the weight of the culture increase during the first 5 hours of growth? How much will the weight of the culture increase from the end of the 5th hour to the end of the 10th hour of growth? The weight increase during the first 5 hours is approximately grams. (Type an integer or decimal rounded to three decimal places as needed)

Problem 9.003 SI At the beginning of the compression process of an air standard Otto cycle, $p_1 = 1$ bar, $T_1 = 300$ K. The maximum temperature in the cycle is 2250 K and the compression ratio is 9.8. The engine has 4 cylinders and an engine displacement of $V_d = 2.1$ L. Determine per cylinder: a) the volume at state 1. b) the air mass per cycle. c) the heat addition per cycle, in kJ. d) the heat rejection per cycle, in kJ. e) the net work per cycle, in kJ. f) the thermal efficiency. g) the mean effective pressure, in bar. h) Develop a full exergy accounting per cycle, in kJ. Let $T_0 = 300$ K, $p_0 = 1$ bar. i) Devise and evaluate the exergetic efficiency for the cycle.
