In studying his campaign plans, Mr. Singleton wishes to estimate the difference between men's and women's views regarding his appeal as a candidate. He asks his campaign manager to take two random independent samples and find the 80%80% confidence interval for the difference. A random sample of 508508 male voters and 605605 female voters was taken. 108108 men and 193193 women favored Mr. Singleton as a candidate. Find this confidence interval.
Step 2 of 4 :
Find the critical value that should be used in constructing the confidence interval.
Pharmaceutical companies promote their prescription drugs using television advertising. In a survey of 90 randomly sampled television viewers, 9 indicated that they asked their physician about using a prescription drug they saw advertised on TV.
Develop a 90% confidence interval for the proportion of viewers who discussed a drug seen on TV with their physician. (Round your answers to 3 decimal places.)
Is it reasonable to conclude that 30% of the viewers discuss an advertised drug with their physician?
Country Financial, a financial services company, uses surveys of adults age 18 and older to determine if personal financial fitness is changing over time (USA Today, April 4, 2012). In February 2012, a sample of 1000 adults showed 410 indicating that their financial security was more than fair. In February 2010, a sample of 900 adults showed 315 indicating that their financial security was more than fair.
State the hypotheses that can be used to test for a significant difference between the population proportions for the two years.
What is the sample proportion indicating that their financial security was more than fair in 2012? In 2010?
Conduct the hypothesis test and compute the p-value. At a .05 level of significance, what is your conclusion?
What is the 95% confidence interval estimate of the difference between the two population proportions?

- A salesman for a new manufacturer of cellular phones claims not only that they cost the retailer less but also that the percentage of defective cellular phones found among his products, ( p1 ), will be no higher than the percentage of defectives found in a competitor's line, ( p2 ). To test this statement, the retailer took a random sample of 185 of the salesman's cellular phones and 150 of the competitor's cellular phones. The retailer found that 22 of the salesman's cellular phones and 11 of the competitor's cellular phones were defective. Does the retailer have enough evidence to reject the salesman's claim? Use a significance level of α=0.05 for the test. Step 1 of 6 : State the null and alternative hypotheses for the test.arrow_forwardResearchers conducted a prospective cohort study to assess the association between dietary supplements and cognitive ability among children. A total of 500 children age 12-17 years who take an omega-3 fatty acid supplement are compared with 500 children age 12-17 years who do not take an omega-3 fatty acid supplement. Researchers follow the children for 2 years. During this time, 300 children who take the supplement earn what is classified as a “high” score on a cognitive test while 200 children who do not take the supplement earn what is classified as a “high” score on the same cognitive test.

Some methods of assessing reading level require estimating the average word length. We've randomly chosen 20 words from a randomly selected page in Intro Stats and counted the number of letters in each word: 5, 5, 2, 11, 3, 5, 6, 8, 5, 4, 7, 2, 9, 4, 8, 10, 4, 7, 6, 9 Suppose that our editor was hoping that the book would have a mean word length of 6.8 letters. Does this sample indicate that the authors failed to meet this goal? With a significance level of 0.05, test an appropriate hypothesis and state your conclusion. (i.e state the appropriate null and alternative hypotheses, calculate the test statistic, conclude and interpret it).arrow_forward

- A group of health professionals produced a cholesterol drug. To measure the effectiveness of this drug they implemented a program that offered free drugs to people to decrease their cholesterol level. Health professionals also collected a sample of people, who did not have the drug, to act as a control group. Health professionals then measured cholesterol level of all individuals in year 1, before any cholesterol drug were given out, and then measured the same group of individuals again in year 2 after the cholesterol drugs had been administered. Consider the following model to evaluate the effectiveness of the drug on people's cholesterol level: cholie = Bo + 8od2, + B1drugit + Vịt chol= cholestrol of individual i, in year t d2;= binary variable equal to 1 if the time period is year 2, and 0 otherwise drug= binary variable equal to 1 if individual i took the drug in year t, and 0 otherwise V= composite error consisting of the unobserved, time-constant effect (a;) and the idiosyncratic…arrow_forwardFewer young people are driving. In 1995, 63.9% of people under 20 years old who were eligible had a driver's license. Bloomberg reported that percentage had dropped to 41.7% in 2016.
