An engineer suspects that a power plant in the city is increasing the air pollution in the vicinity of the plant. A sample of measurements of carbon monoxide (in mg/m3 of air) in the vicinity of the plant (Group 1) is obtained for comparison with another sample obtained from other locations (Group 2) in the city. Dataset is available at pollution.txt↓ Assuming the measurements for both groups follow a normal distribution and the populations' variances are equal, what is the lower bound of a 95% confidence interval for the difference between the means of the first group and the second group. i.e., µ1 − μ₂. Note: Please round your answer to four decimal places.

The summary statistics for a certain set of points are: n= 25, s, = 2.50, E (x-x)¯= 250.12, and b, = 2.15. Assume the conditions of the linear model hold. A 98% confidence interval for B, will be constructed. Part 1 of 4 How many degrees of freedom are there for the critical value? The degrees of freedom for the critical value are 23 Part 2 of 4 What is the critical value? Round the answer to three decimal places. The critical value is 2.500 Part: 2 / 4 Part 3 of 4 What is the margin of error? Round the answer to three decimal places. Margin of error =
A graduate student is interested in how viewing different types of scenes affects working memory. For his study, he selects a random sample of 36 adults. The subjects complete a series of working memory tests before and after walking in an urban setting. Before the walk, the mean score on the test of working memory was 9.1. After the walk, the mean score was 1.4 higher. The graduate student has no presupposed assumptions about how viewing different types of scenes affects working memory, so he formulates the null and alternative hypotheses as: H00 : μDD = 0 H11 : μDD ≠ 0 Assume that the data satisfy all of the required assumptions for a repeated-measures t test. The graduate student calculates the following statistics for his hypothesis test: Mean difference (MDD) 1.4 Estimated population standard deviation of the differences (s) 1.6 Estimated standard error of the mean differences (sMDMD) 0.2667 Degrees of freedom (df) 35 The t statistic 5.25 The critical values of t…

8. A confidence interval for estimating the mean An industrial/organizational psychologist wants to improve worker productivity for a client firm, but first he needs to gain a better understanding of the life of the typical white-collar professional. Fortunately, he has access to the 2008 Workplace Productivity Survey, commissioned by LexisNexis and prepared by WorldOne Research, which surveyed a sample of 650 white-collar professionals (250 legal professionals and 400 other professionals). One of the survey questions was, “How many work-related emails do you receive during a typical workday?” For the subsample of legal professionals (n = 250), the mean response was M = 36.7 emails, with a sample standard deviation of s = 23.8 emails. The estimated standard error is sMM? = A-0.085, B-1.341, C-0.095 or D-1.505 (choices to choose from.) . Use the following Distributions tool to develop a 90% confidence interval estimate of the mean number of work-related emails legal…
