Hello,I'm having trouble calculating the pooled sample porportion A sample of 522 school teachers, who are married, showed that 221 of them hold a second job to supplement their incomes.Another sample of 401 school teachers, who are single, showed that 134 of them hold a second job to supplement their incomes.The null hypothesis is that the proportions of married and single school teachers who hold a second job to supplement theirincomes are not different. The alternative hypothesis is that the proportions of married and single school teachers who hold asecond job to supplement their incomes are different. The significance level is 5%.What is the value of the pooled sample proportion, rounded to four decimal places?

You may need to use the appropriate appendix table or technology to answer this question. In 2017, a website reported that only 10% of surplus food is being recovered in the food-service and restaurant sector, leaving approximately 1.5 billion meals per year uneaten. Assume this is the true population proportion and that you plan to take a sample survey of 555 companies in the food service and restaurant sector to further investigate their behavior. (a) Specify the distribution form and parameters of the sampling distribution of p, the proportion of food recovered by your sample respondents. (Round your answer for to four decimal places.) E(P) - % Since no and n(1-0)- approximating the sampling distribution with a normal distribution appropriate in this case. (b) What is the probability that your survey will provide a sample proportion within 20.03 of the population proportion? (Round your answer to four decimal places.) (c) What is the probability that your survey will provide a…
Please answer the following questions on sampling. List and explain up to three advantages of applying statistical sampling techniques to audit testing. The advantages of statistical sampling over non statistical sampling include assisting the auditors in (1) designing efficient samples, (2) measuring the sufficiency of the evidence obtained, and (3) objectively evaluating sample results. I need to figure out how to explain these three advantages with at least two sentences further explaining each advantage for a total of at least six extra sentences explaining these advantages. Please help me as soon as possible. Thank you for the previous help.

webassign.net/web/Student/Assignment-Responses/submit?pos=10&dep=22704121&tags=autos A newspaper infographic titled "Social Media Jeopardizing Your Job?" summarized data from a survey of 1,825 recruiters and human resource professionals. The infographic indicated that 53% of the people surveyed had reconsidered a job candidate based on his or her social media profile. Assume that the sample is representative of the population of recruiters and human resource professionals in the United States. (a) Use the given information to estimate the proportion of recruiters and human resource professionals who have reconsidered a job candidate based on his or her social media profile using a 95% confidence interval.

As an analyst, we would like to perform a work sampling study on an assembly line. The jobs can bedifferentiated on the basis of the product size: A, B, and C. We perform a study over a five-week periodthat equals to 200 working hours. There are 12 workers to be examined. In total, we perform 1140observations. Yet, the worker absences lead to 15 worker-day deduction from the total working hourswhere workers work 8 hour each day. The study results are tabulated below. Q: For the C size product, construct a 96% confidence interval about the mean assembly time per productin terms of hours.a) (0,3702 0,4298)b) (0,4004 0,3996)c) (0,1805 0,1209)d) (0,3746 0,4254)e) (0,1253 0,1761)
