Suppose that I want to estimate the percentage of students who love statistics in California. How many students would I need to survey in order to have a margin of error that is less than 3%, assuming that I want to be 90% confident in the final results.
Many investors and financial analysts believe the Dow Jones Industrial Average (DJIA) gives a good barometer of the overall stock market. On January 31, 2006, 9 of the 30 stocks making up the DJIA increased in price (The Wall Street Journal, February 1, 2006). On the basis of this fact, a financial analyst claims we can assume that 30% of the stocks traded on the New York Stock Exchange (NYSE) went up the same day.A sample of 58 stocks traded on the NYSE that day showed that 21 went up.You are conducting a study to see if the proportion of stocks that went up is is significantly more than 0.3. You use a significance level of α=0.02.What is the test statistic for this sample? (Report answer accurate to three decimal places.)test statistic = What is the p-value for this sample?

In a study conducted by a human resource management organization, 492 human resource professionals were surveyed. Of those surveyed, 83% said that their companies conduct criminal background checks on all job applicants. Complete parts (a) through (d). Question content area bottom Part 1a. What is the exact value that is 83% of 492 survey subjects?
Suppose Laura, a facilities manager at a health and wellness company, wants to estimate the difference in the average amount of time that men and women spend at the company's fitness centers each week. Laura randomly selects 15 adult male fitness center members from the membership database and then selects 15 adult female members from the database. Laura gathers data from the past month containing logged time at the fitness center for these members. She plans to use the data to estimate the difference in the time men and women spend per week at the fitness center. The sample statistics are summarized in the table. Population Populationdescription Population mean(unknown) Samplesize Sample mean(min) Sample standarddeviation (min) 11 male μ1 n=15 x¯1=137.7 s=51.7 22 female μ2 n=15 x¯2=114.6 s=34.2 df=24.283 The population standard deviations are unknown and unlikely to be equal, based on the sample data. Laura plans to use the two-sample ?-t-procedures to estimate the…
The Humane Society is interested in finding out how many households in America have at least one cat. How many households must be surveyed to be 95% confident that the estimate will be within 4% of the true population percentage?
In 2016 the Better Business Bureau settled 84% of complaints they received in the United States. Suppose you have been hired by the Better Business Bureau to investigate the complaints they received this year involving new car dealers. You plan to select a sample of new car dealer complaints to estimate the proportion of complaints the Better Business Bureau is able to settle. Assume the population proportion of complaints settled for new car dealers is 0.84, the same as the overall proportion of complaints settled in 2016. Use the z-table. a. Suppose you select a sample of 200 complaints involving new car dealers. Show the sampling distribution of p. E(p) (to 2 decimals) (to 4 decimals) b. Based upon a sample of 200 complaints, what is the probability that the sample proportion will be within 0.04 of the population proportion (to 4 decimals)? probability : = c. Suppose you select a sample of 460 complaints involving new car dealers. Show the sampling distribution of p. E(F) (to 2…

suppose the five number summary for the normal annual precipitation (in inches) for 12 different U.S. cities is the following: 5.1, 11.5, 16, 22.1, 51.7 A. The IQR is 10.6 This means that the difference between the largest an smallest amount of rainfall is 10.6 inches B. The IQR is 10.6 This means that the range of the middle 50% of rainfall values is 10.6 inches. C. The IQR is 46.6 This means that the difference between the largest and smallest amount of rainfall is 46.6 D. The IQR is 46.6 This means that the range of the middle 50% of rainfall is 46.6 inches.
Approval 2008. Of all the post–World War II presidents,Richard Nixon had the highest disapproval rating near theend of his presidency. His disapproval rating peaked at 66% in July 1974, just before he resigned. This percent-age has been considered by some pundits as a high water mark for presidential disapproval. However, in April 2008,George W. Bush’s disapproval rating peaked at 69%,according to a Gallup poll of 1016 voters. Pundits starteddiscussing whether his rating was discernibly worse thanthe previous high water mark of 66%. What do you think?
The website Data USA stated that in 2016, Texas had the lowest number of adults with a serious mental illness with an average of M=3.26% of the population affected. The state of Texas wants to test if they have a significantly decreased number of mental illness patients compared with the states with the (n=8) highest level of mental illness found. In 2016 the following states had the highest level of adult patients with mental illness: Arkansas= 5.45%, Montana=5.34%, Vermont=5.32%, Oregon=5.19%, Utah=5.2%, Ohio=5.13, Kentucky=5.25% West Virginia=5.18%. The alpha level for the study was set to α=.05 for the criteria. a. State the hypotheses of the study. b. Find the critical t value for this study c. Compute the one-sample t test. (Again calculate sample SD or s - and get SEM before calculating t.) d. Compute the Cohen's d for the data (even if not significant) e. State the results - is the sample significantly higher? Do you reject the null hypothesis? Report the t test results in APA…
