A random sample of n = 1,400 observations from a binomial population produced x = 523. (a) If your research hypothesis is that p differs from 0.4, what hypotheses should you test? $H_0: p < 0.4$ versus $H_a: p > 0.4$ $H_0: p \neq 0.4$ versus $H_a: p = 0.4$ $H_0: p = 0.4$ versus $H_a: p < 0.4$ $H_0: p = 0.4$ versus $H_a: p \neq 0.4$ $H_0: p = 0.4$ versus $H_a: p > 0.4$ (b) Calculate the test statistic and its p-value.

7. Assume that you are a scientist hire to evaluate changes in materials and you are given the following situation. Between 32° F and 212° C, the heat capacity of Hg is given by: $C_{p,m} = 30.093 - 4.944 \times 10^{-3} \frac{T}{K}$ $\frac{J}{K \cdot mol^{-1}}$ Calculate $\Delta H$ and $\Delta S$ if 1.75 moles of Hg(l) are raised in temperature from 10° C to 150.0° C at constant pressure (10 points). Explain the meaning of your numerical answer (5 points).

Question 4 1 pts A coach wants to know whether playing video games improves reaction time on the field. They split the team into two groups. Fifteen of the players are told to play an action-based video game for 1 hour each day. The other 15 players are told to abstain from video games. The experiment lasts 6 weeks, and at the end, the players are tested to see what their reaction time on the field is. In this study, the independent variable would be _____, and the dependent variable would be 1 hour of video games each day; 6 weeks playing video games; reaction time on the field 16 players who played a video game; 15 players who did not play video games reaction time on the field; playing video games

Homework: MSL #8 Question 12, 6.2.17-T Part 1 of 3 HW Score: 66.67%, 10 of 15 points Points: 0 of 1 Save In a random sample of 17 people, the mean commute time to work was 33.2 minutes and the standard deviation was 7.2 minutes. Assume the population is normally distributed and use a t-distribution to construct a 98% confidence interval for the population mean µ. What is the margin of error of µ? Interpret the results. The confidence interval for the population mean µ is (\boxed{\hspace{0.5cm}}, \boxed{\hspace{0.5cm}}). (Round to one decimal place as needed.)
