A confidence interval for estimating the meanAaAaAn industrial/organizational psychologist wants to improve worker productivity for a client firm, but first he needs togain a better understanding of the life of the typical white-collar professional. Fortunately, he has access to the 2008Workplace Productivity Survey, commissioned by LexisNexis and prepared by WorldOne Research, which surveyed asample of 650 white-collar professionals (250 legal professionals and 400 other professionals).One of the survey questions was, "During the average workday, how many hours do you spend attending meetings?"For the subsample of legal professionals (n = 250), the mean response was M = 2.0 hours, with a sample standarddeviation of s = 4.2 hours.The estimated standard error is sM =Jse the following Distributions tool to develop a 95% confidence interval estimate of the mean number of hours legalprofessionals spend attending meetings during a typical workday.

Given: n=250, M=2.0, s=4.2 The estimated standard error is given by, sM=sn=4.2250=0.2656 Hence, the…

You are interested in constructing a 95% confidence interval for the proportion of all caterpillars that eventually become butterflies. Of the 405 randomly selected caterpillars observed, 54 lived to become butterflies. Round answers to 4 decimal places where possible. a. With 95% confidence the proportion of all caterpillars that lived to become a butterfly is between and . b. If many groups of 405 randomly selected caterpillars were observed, then a different confidence interval would be produced from each group. About percent of these confidence intervals will contain the true population proportion of caterpillars that become butterflies and about percent will not contain the true population proportion.
Suppose we wish to calculate an 80% confidence interval. What would be the value of z in the confidence interval equation p(1-p) p ± ²√ -? Use the z-score table to find it. Your answer should be correct to within 0.01. Your value of z should be positive. n
IMR in Singapore. The infant mortality rate (IMR) is the number of infant deaths per 1000 live births. Suppose that you have been commissioned to estimate the IMR in Singapore. From a random sample of 1109 live births in Singapore, you find that 0.361% of them resulted in infant deaths. You next find a 90% confidence interval: or 0.000647 to 0.00657. You then conclude, “I can be 90% confident that the IMR in Singapore is somewhere between 0.647 and 6.57.” How did you do?
Now you are interested in the percent of dogs that were neutered in your sample. For 40 dogs, 30 of them were neutered. What is the LOWER limit for this confidence interval? The statistical value you will need is 1.96. Give your answer as 0.XX

Elvin wants to know how the school views him as their leader. He asked his friend, Marcus, to research it. After a week, Marcus told him that a sample of 400 schoolmates selected at random indicated that 58% of them hold him in high regard. Determine the confidence interval at 60% confidence level.
Tina catches a 14-pound bass. She does not know the population mean or standard deviation. So she takes a sample of five friends and they say the last bass they caught was 9, 12, 13, 10, and 10 pounds. Find the t and calculate a 95% (α = .05) confidence interval.
suppose that you take 1000 simple random samples from a population and that, for each sample, you obtain a 95% confidence interval for an unknown parameter. Approximately how many of those confidence intervals will continue the value of the unknown parameter?
Sal knows that parties of people on average spend 75 minutes at their restaurant. They wonder if this average is significantly different on the weekends. They found the average time spent by the 30 parties which dined there this weekend was 82 minutes with a SD of 17 minutes. Assume an alpha of .05. The lower end of the 95% confidence interval is and the higher end of the 95% confidence interval is.
If n=�=25, ¯x=�¯=45, and s=�=6, find the margin of error E� at a 95% confidence level. Give your answer to at least two decimal places.
Suppose that you wanted to know if the percentage of people who will attend a sporting event this year will decrease. Last year, 43% of Americans attended a sporting event. After taking a sample, you attain a sample percentage of 18% with a margin of error of 3%. Construct a confidence interval and use that interval to determine if the number of Americans who will attend a sporting event has decreased. Show your calculation for the interval and then state your conclusion in complete sentences.
Suppose you obtained the heights of ten women and calculated a confidence interval from this information. Without knowing the population mean μ, would you have any way of knowing for certain if your interval actually contained the value μ? Why and why not?
