- A surprising fact is that only 56% of all teens use a password on their mobile device. If a poll chooses a simple random sample of teens and asks if they use a password on their mobile device, the percent who say “Yes” will vary from sample to sample, if the sampling is repeated. In fact, if we look at the sampling distribution in this case, we will see that the percent “Yes” in many samples of the same size will follow a Normal distribution, with a mean of 56% and a standard deviation of 1.6% Although the results will vary if the poll is repeated, the distribution of results is centered at the truth about the population(56 percent). We call this desirable property of a simple random sample A)The confidence level B) low variability C)lack of bias D)symmetryThe estimated standard error of the mean for a relevant sampling distribution provides an indicator of: The average or standard amount we expect a sample mean to differ from the population mean, if the null hypothesis is true The average or standard amount we expect two study condition means to differ from one another in a repeated measures study design due to chance, if the null hypothesis is true All of these answers are correct The average or standard amount we expect two sample group means to differ from one another in an independent groups study design due to chance, if the null hypothesis is trueSuppose the true proportion of voters in the county who support a school levy is 0.53. Consider the sampling distribution for the proportion of supporters with sample size n = 101.What is the mean of this distribution? What is the standard error of this distribution?
- R4Airlines tend to overbook their flights because they assume a certain percentage of people will be 'no shows' due to change in plans or late connecting flights. A recent study suggested that 86% of people actually show up for their flight on time. A random sample of 222 booked passengers is taken and whether or not they showed up on time is recorded for each of them. The Central Limit Theorem for proportions says that the sampling distribution of the proportion of people who show up on time for their flight will have a Normal shape. (a) Give the center and standard error for the sampling distribution of proportions. Round to four decimal places as needed. mean = and standard error = (b) What is the probability that at least 88% of the randomly selected booked passengers showed up on time?

- Kindly answer itAt a large university, 68% of the students have a laptop, while only 43% of professors have one. Let and be the sample proportions of students and professors, respectively, who have a laptop. Suppose 56 students and 31 professors from this university are selected at random and asked if they have a laptop. Which of the following is the correct calculation and interpretation of the standard deviation of the sampling distribution of ? The difference (student – professor) in the sample proportions of those who have a laptop typically varies about 0.012 from the true difference in proportions. The difference (student – professor) in the sample proportions of those who have a laptop typically varies about 0.035 from the true difference in proportions. The difference (student – professor) in the sample proportions of those who have a laptop typically varies about 0.109 from the true difference in proportions. The difference (student – professor) in the sample proportions of those who…Suppose the above bell curve (normal distribution) represents the voters and their viewpoints (the "height" of the curve represents the number of voters with that particular view) on the highly debated issue for an upcoming election for a member of Congress. The two candidates's (A and B) views on the issue are as indicated; your opinion on the issue is represented by the "green line." Who will you vote for in the election? Why do you prefer that candidate over the other? According to the Median Voter Theory, which candidate will win the election? Why will that candidate win (why will they receive the majority of votes)?
