Please see below. Note that I am only given one attempt at this and I believe that the answer I have may not be correct. In selecting the sample size to estimate the population proportion pp, if we have no knowledge of even the approximate value of the sample proportion p̂ p^, we:A. take two more samples and find the average of their p̂ p^B. let p̂ =0.95p^=0.95C. let p̂ =0.50p^=0.50D. take another sample and estimate p̂ p^ Under which of the following circumstances is it impossible to construct a confidence interval for the population mean?A. A normal population with a large sample and a known population variance.B. A normal population with a small sample and an unknown population variance.C. A non-normal population with a large sample and an unknown population variance.D. A non-normal population with a small sample and an unknown population variance.

ou are being consulted by a level 400 psychology student on her final project. Her work entails estimating the proportion of students in University of Ghana who are claustrophobic i.e. having an extreme or irrational fear of confined places. What is the population in her case?Would you advise a complete enumeration of the population or a survey? Give reasons.Describe a sampling method you think will help her obtain the best estimate of the proportion of claustrophobic students in population. Justify the selected sampling method and enumerate its advantages over at least one other sampling method you know.

Can i get help with this problem? the sample proportion denoted phat is given by the formula phat(p-hat)=x/n where x s the number of individuals with a specified characteristic in a sample of n individuals. 1. find: phat(p-hat_ if the students poll surveyed 1200 people that vacation during the summer and asked if they plan to work while on vacation. Of those surveyed, 552 indicated that they plan to work on vacation. Find the sample proportion of individuals polled that plan to work on vacation. So, Students estimates that from the value of phat(p-hat) found above that ____________ or ________ % of adults who vacation plan to work on vacation,

Please check with the instructor for approval before taking your data. You may do this project alone or with another person in the class. Take a sample of 30 from the population in which you are concerned. If possible, make your sample a SRS (simple random sample). Then present the following information for your project: State the topic your project is about and the audience surveyed. State the exact question you asked in your survey. Compute the proportion for your sample. Show your computation. Find a 95% confidence interval for p. What is the margin of error for this confidence interval? What is the meaning of this interval with respect to your data and project? Construct and perform a hypothesis test for p at the…
