to the lack of trials.Do you have a guess for the real value of p?Due to the high number of trials done in the previous question, I assume the value of p to benear 0.6.3.The company Digital Trends reported that 48% of Americans have shared passwords forTV and movie streaming ("Americans Know They Shouldn't Share Their Passwords, But DoIt Anyway," February 18, 2016). For purposes of this exercise, assume thatthe 48% figure is correct for the population of adult Americans.A. A random sample of size n = 200 will be selected from this population and , the proportionwho have shared TV and movie streaming passwords, will be calculated. What are the meanand standard deviation of the sampling distribution of ? Round to 3 decimal places asneeded.1B. Is the sampling distribution of approximately normal for random samples of size 200?Explain.C. Suppose that the sample size is n= 50 rather than n = 200. Does the change in sample sizeaffect the mean and standard deviation of the sampling distribution of p? If so, what are thenew values of the mean and standard deviation? If not, explain why not.D.

You are interested in comparing sleep habits of elementary school children. Suppose you have agroup of eighth graders. You asked them in July to estimate about how many hours of sleep they get pernight, on average. You asked those same individuals the same question again in November, during theschool year. Which is the most appropriate test to use?
GSS 2018 respondents were asked to rate their level of agreement to the statement, “Differences in income in America are too large.” Responses were measured on a 5-point scale: 1 = strongly agree, 2 = agree, 3 = neutral, 4 = disagree, and 5 = strongly disagree. Strong Democrats had an average score of 1.69 (s = 1.04, N = 86) while strong Republicans had an average score of 2.11 (s = 1.05, N = 67). The estimated standard error of the difference between meansis 0.17. What is the appropriate test statistic? Why? Test the null hypothesis with a one-tailed test (strong Democrats are more likely to agree with the statement than strong Republicans); α = .05. What do you conclude about the difference in attitudes for these two political groups? If you conducted a two-tailed test with α = .05, would your decision have been different?

Support for the U.S. death penalty for convicted murderers was 63% in 2014 (Gallup poll results 2018). In a recent survey of 150 randomly selected U.S. adults, 75 said they were in favor of the death penalty for those convicted of murder. Does this sample appear to come from a population with a lower proportion in favor of the death penalty? d) Say that a = 0.05, what does this mean. Explain in the context of the problem. e) What would it mean to make a type II error? Explain in the context of this problem. f) Use a 0.05 significance level to test the claim. State your conclusion AND interpret your results.

A time study analyst observed a repetitive work cycle performed by a worker. During the observation, the analyst made a record of the work elements. She also made a note of the worker's performance and rated it as 95%. Back in the office, the analyst listed the basic motion elements for the task and the sum of the normal times for the basic motion elements was 1.38 minutes. The company uses a PFD allowance factor of 15%. What is the standard time for the task? Tstd 1.225 minutes/unit Tstd 1.587 minutes/unit Tstd 0.625 minutes/unit Tstd 1.959 minutes/unit =
