We want to test whether the proportion of people who failed in the current sample is statistically different from the proportion who failed in previous years. Is the average failure rate still 20% or not? Assuming a two-tailed test, what are the null and alternative hypothesis? (a) Ho: p=0.20; H₁: p > 0.20 (b) Hop= 0.12; H₁ : p = 0.12 (c) Ho: p = 0.20; H₁ p / 0.20 (d) Ho p0.12; H₁ p = 0.12 (e) None of the above

You may need to use the appropriate appendix table or technology to answer this question. Fewer young people are driving. In year A, 62.9% of people under 20 years old who were eligible had a driver's license. Twenty years later in year B that percentage had dropped to 48.7%. Suppose these results are based on a random sample of 1,500 people under 20 years old who were eligible to have a driver's license in year A and again in year B. (a) At 95% confidence, what is the margin of error of the number of eligible people under 20 years old who had a driver's license in year A? (Round your answer to four decimal places.)

College Degree Recipients A survey of 800 recent degree recipients found that 158 received associate degrees; 451, bachelor degrees, 21 first-professional degrees; 154, master degrees; and 16, doctorates. Is there sufficient evidence to conclude that at least one of the proportions differs from a report which stated that 23.3% were associate degrees; 51.1%, bachelor degrees; 3%, first professional degrees; 20.6%, master degrees; and 2%, doctorates? Use =α0.10.

A vaccine to prevent a severe virus was given to children within the first year of life as part of a drug study. The study reported that of the 3456bchildren randomly assigned the vaccine, 58 got the virus. Of the 1606 children randomly assigned the placebo, 46 got the virus. a. Find the sample percentage of children who caught the virus in each group. Is the sample percentage lower for the vaccine group, as investigators hoped? b. Determine whether the vaccine is effective in reducing the chance of catching the virus, using a significance level of 0.01.The first few steps of the hypothesis-testing procedure are given. Complete the procedure.
A study considered the question, "Are you a registered voter?" Accuracy of response was confirmed by a check of city voting records. Two methods of survey were used: a face-to-face interview and a telephone interview. A random sample of 84 people was asked the voter registration question face-to-face. Seventy respondents gave accurate answers (as verified by city records). Another random sample of 74 people was asked the same question during a telephone interview. Sixty-five respondents gave accurate answers. Assume that the samples are representative of the general population. Note: For degrees of freedom d.f. not in the Student's t table, use the closest d.f. that is smaller. In some cases, this choice will increase the P-value by a small amount or increase the length of the confidence interval, thereby making the answer slightly more "conservative."(a) Let p1 be the population proportion of all people who answer the voter registration question accurately during a face-to-face…

Es A census of all the 12,475 current students at the local community college showed that 56.5% want to transfer to a university, their average age is 21.7 years, and 60 of them are pursuing degrees in mathematics. In order to attract more students, the math department organized an "Opportunities in Mathematics" fair for current students of the college. A total of 267 students from those who attended responded to a poll. The poll showed that 83% of those who answered want to transfer to a university, the average poll respondent was 22.3 years old, and 77 them were interested in pursuing a degree in mathematics. (a) For the math fair poll, identify the population and the sample. Population: (Choose one) Sample: (Choose one) (b) Choose whether each number described below is a parameter or a statistic for the math fair poll.
