first group was set up to be “right” in its eyewitness accounts and the second group was set up to be“wrong”; the desire was to see if confidence differed across groups. Thirty-four participants wererecruited from a college campus and randomly divided into two groups, both of which were shown avideo of a crime scenario (length: 58 seconds) in which the perpetrator’s facial characteristics (withrespect to the camera) were clearly visible at two separate points and sporadically visible at others. Halfthe participants then were shown a five-individual lineup that contained the perpetrator in the video(“Group A”), and half the participants were shown a five-individual lineup that did not contain theperpetrator (“Group B”). Participants were asked to (a) identify if and where the perpetrator was in thelineup and (b) provide a rating of confidence on a scale from 1 to 10 (10 being highly confident) that theselection was the same as the person seen in the video committing the crime.

The times of london reported on 4 January 2002 that Polish mathematicians recorded 140 heads in 250 spins (56%) of the Belgian one euro coin, suggesting that it was unbalanced; this touched off an international media frenzy. a. test the null hypothesis that the true probability of heads is equal to 0.5 b. Place a 95% confidence interval around the sample proportion
Statewide, social workers average 10.2 yearsof experience. In a random sample, 203 socialworkers in greater metropolitan Shinbone averageonly 8.7 years, with a standard deviation of 0.52.Are social workers in Shinbone significantly lessexperienced? (NOTE: The wording of the researchhypothesis may justify a one-tailed test of significance. For a one-tailed test, what form would theresearch hypothesis take, and where would thecritical region begin?
A credit company has gathered information regarding the average amount (in $) owed by peopleunder 30 years of age and by people over 30 years by taking independent random samples fromboth age groups. You are given the following information. Under 30 Over 30sample mean 600 550n 200 300σ2 361 400Construct a 95% confidence interval for the difference between the population average amountsowed by the two age groups.
A simple random sample of size n=400 individuals who are currently employed is asked if they work at home at least once per week. Of the 400employed individuals surveyed, 30 responded that they did work at home at least once per week. Construct a 99% confidence interval for the population proportion of employed individuals who work at home at least once per week
In a previous study, it was found that p-hat=0.68 for a particular sample. Suppose we would like to repeat this study. Give the sample size n required to have margin of error equal to .01, at the 95% confidence level.
A random sample of male and female employees selected from a large industrial plant yielded the followinghourly wage results (in Rands):Male Femalen1 = 45 n2 = 32x1 = 6.00 x2 = 5.75s1 = 0.95 s2 = 0.75Question 1Calculate the difference in the sample means (rounded off to two decimals)? Question 2Construct and explain a 99% confidence interval for the difference between the population mean hourlywages for all male and female employees (rounded off to four decimals). Question 3Is there a significant difference in the two population means, considering the confidence interval found inQuestion 2?
A paper reported that in a representative sample of 289 American teens age 16 to 17, there were 77 who indicated that they had sent a text message while driving. For purposes of this exercise, assume that this sample is a random sample of 16- to 17-year-old Americans. Do these data provide convincing evidence that more than a quarter of Americans age 16 to 17 have sent a text message while driving? Test the appropriate hypotheses using a significance level of 0.01. (Round your test statistic to two decimal places and your P-value to four decimal places.) z = P-value =
If n = 340 and ˆpp^ (p-hat) = 0.6, construct a 95% confidence interval. According to the Oxnard College Student Success Committee report in the previous year, we believe that 21% of students struggle in their classes because they don't spend more than 8 hours studying independently outside of a 4-unit class. For this year, you would like to obtain a new sample to estimate the proportiton of all Oxnard students who struggle in their classes because they don't study enough outside of the classrooms. You would like to be 99% confident that your estimate is within 5% of the true population proportion. How large of a sample size is required? Do not round mid-calculation.
