A sample of 62 city blocks were taken in Black majority neighborhoods and 58 city blocks in non-Blackmajority neighborhoods. We are interested in looking at the concentration of Nitrogen Dioxide (NO2), an airpollutant. The average amount of NO2 in Black majority blocks is 11.0362 with a standard deviation of4.3976, and the average amount of NO2 in non-Black majority blocks is 10.4195 with a standard deviationof 4.9371. Test the claim that the mean NO2 concentration is greater in Black majority than non-Blackmajority blocks at a = 0.10.Assume that the data come from normal populations with equal variances.

The combined SAT scores for the students at a local high school are normally distributed with a mean of 1521 and a standard deviation of 301. The local college includes a minimum score of 888.9 in its admission requirements. What percentage of students from this school earn scores that fail to satisfy the admission requirement?
Researchers at a medical center studied the amount of caffeine, in milligrams (mg), contained in a 16-ounce cup of coffee made at one machine at the center’s cafeteria. They selected a random sample of 40 16-ounce cups of coffee made at different times of the day during a one-month period. The mean and standard deviation of the amount of caffeine in the sample were 159.88 mg and 36.72 mg, respectively. A graph of the sample data revealed a right skew with one outlier. The researchers will construct a confidence interval to estimate the amount of caffeine for all 16-ounce cups made at the machine. Which of the following conditions is not needed for the inference? A. The samples were selected at random. B. The observations are independent of one another. C. The sample size of 40 is less than 10% of the population size. D. The graph of the sample data is symmetric with no outliers. E. The sample size is large enough to assume that the sampling distribution of sample means is…
An article reports an investigation into the toxicity of bilirubin on several cell lines. Ten sets of human liver cells and 5 sets of mouse fibroblast cells were placed into solutions of bilirubin in albumin with a 1.4 bilirubin/albumin molar ratio for 24 hours. In the 10 sets of human liver cells, the average percentage of cells surviving was 53.9 with a standard deviation of 10.7. In the 5 sets of mouse fibroblast cells, the average percentage of cells surviving was 73.1 with a standard deviation of 9.1. Let μXμX represent the population mean for the mouse cells and let μYμY represent the population mean for the human cells. Find a 98% confidence interval for the difference μX−μYμX−μY . Round down the degrees of freedom to the nearest integer and round the answers to three decimal places. The 98% confidence interval is ( , ).
Polychlorinated biphenyl (PCB) is among a group of organic pollutants found in a variety of products, such as coolants , insulating materials , and lubricants in electrical equipment. Disposal of the items containing less than 50 parts per million ( ppm) PCM is generally not regulated . A certain kind of small capacitor contains PCB with a mean of 48.2 ppm and a standard deviation of 8 ppm. The Environmental Protection Agency takes a random sample of 37 of these small capacitors , planning to regulate the disposal of such capacitors if the sample mean amount of PCB is 49 ppm or more . Find the probability that the disposal of such capacitors will be regulated. Carry your intermediate computations to at least four decimal places. Round your answer to at least three decimal places .
Condé Nast Traveler conducts an annual survey in which readers rate their favorite cruise ship. All ships are rated on a 100-point scale, with higher values indicating better service. A sample of 37 ships that carry fewer than 500 passengers resulted in an average rating of 85.35, and a sample of 43 ships that carry 500 or more passengers provided an average rating of 81.60. Assume that the population standard deviation is 4.54 for ships that carry fewer than 500 passengers and 3.99 for ships that carry 500 or more passengers. Round your all answers to two decimal places. a. What is the point estimate of the difference between the population mean rating for ships that carry fewer than 500 passengers and the population mean rating for ships that carry 500 or more passengers? b. At 95% confidence, what is the margin of error? c. What is a 95% confidence interval estimate of the difference between the population mean ratings for the two sizes of ships? to
