There is a very popular lottery in which a ticket is called a scratcher. In this lottery, 47% of the scratchers are winning ones. Suppose that we will take arandom sample of 7 scratchers. Let p represent the proportion of winning scratchers from the sample. Consider the sampling distribution of the sampleproportion p.Complete the following. Carry your intermediate computations to four or more decimal places. Write your answers with two decimal places, rounding if needed.(a) Find la (the mean of the sampling distribution of the sample proportion).Ha = 0(b) Find on (the standard deviation of the sampling distribution of the sample proportion).On =||?

Solution: Given that: p= 0.47 Population proportion n= 7 Sample size

Answered: There is a very popular lottery in…

Netflix is considering a new romcom (romantic comedy) series. Before making a final decision, the producers design an experiment to estimate the proportion of viewers who would watch the series. A random sample of 680 viewers was selected and asked to watch the first two episodes. After viewing the episodes, 425 viewers indicated they would watch the new series.

i did all info in below 1 and 2 i just need questions 3,4,5 done ESTIMATION OF A POPULATION PROPORTION project 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 significance level . What conclusions can you draw from this test? 1.i asked 40 random people if they got pulled over in a school zone did they get a ticket 30 said no 10 said yes 2.when you got pulled over in a school zone did you recive a ticket
