32% of employees judge their peers by the cleanliness of their workspaces. You randomly select & employees and ask them whether they judge their peers by the cleanliness of their workspaces. The random variable represents the number of employees who judge their peers by the cleanliness of their workspaces. Complete parts (a through (c) below.

Suppose that the insurance companies randomly surveyed 400 drivers and found that 320 claimed they always buckle up. We are interested in the population proportion of drivers who claim they always buckle up.  Use this scenario for the next 4 questions.   What is the meaning of p ^ in the context of this scenario? Group of answer choices the proportion of drivers who claim they always buckle up in the POPULATION Neither of these the proportion of drivers who claim they always buckle up in the SAMPLE   What is the value of p ^ in the context of this scenario? f you wanted to estimate the true percentage of drivers who claim they always buckle up to within 1% error with 95% confidence, how many drivers would you need to survey?  You may use the pilot study as a preliminary estimate of p ^.

percentage may be now, so a of 250 of last year's freshmen 4. 78% of all to in Fall 2015. You think that the a and tind that 84% returned, www.csun.edu/counts/one_year_continuation_rate-plip a. What is p? _ What is the number of successes? What is n? b. Write the hypotheses: Circle the best definition of p. the proportion of all of last year's freshmen who returned the proportion of all 2014 CSUN freshmen who returned the proportion of all CSUN freshmen among the 250 who returned C. Assuming that Ho is true, the sampling distribution of p has a mean of Use the formula to compute the SE of the sampling distribution of p. Complete this sketch of the sampling distribution of p. Put a scale on the horizontal axis. Then locate the result from the sample and shade in area representing the p-value. (Is the area representing the p-value on one side or two sides?) Use StatCrunch to find the p-value for this situation. e. Is there statistically significant evidence that the percentage is…

There are 10 eggs with different colors in each basket. A child randomly chooses 1 egg from each basket. Explain fully whether or not the binomial distribution can be applied to the problem of randomly choosing 3 green eggs from 5 baskets

I am working in excel and using the binomial dist. The problem is:  A lightbulb factory produces 1,000 lightbulbs every hour. Approximately 0.5% of the lightbulbs are defective, and do not work. Use the binomial distribution to determine the odds each respective outcome below. Then answer the questions. Distribution table is 1-15. For my equation, what is:number_strials probability cumulative

78​% of U.S. adults think that political correctness is a problem in America today. You randomly select six U.S. adults and ask them whether they think that political correctness is a problem in America today. The random variable represents the number of U.S. adults who think that political correctness is a problem in America Find the variance of the binomial distribution.     σ2=nothing   ​(Round to the nearest tenth as​ needed.)
