An insurance company selected samples of clients under 18 years of age and over 18 and recorded the number of accidents they had in the previous year. The results are shown below. Under Age 18 Over Age 18 n1 = 500 n2 = 600 Number of accidents = 180 Number of accidents = 150 We are interested in determining if the accident proportions differ between the two age groups.
Use the results from a survey of a simple random sample of 1001 adults. Among the 1001 respondents, 67% rated 13 themselves as above average drivers. We want to test the claim that of adults rate themselves as above average drivers. Complete parts (a) through (c). 20 a. Identify the actual number of respondents who rated themselves as above average drivers. (Round to the nearest whole number as needed.)
Answer: A researcher surveyed 80 randomly selected Certified Public Accountants in each of the cities in Metro Manila area and asked them if they have performed work for free for 10 or fewer clients in the last year. The results are shown in the table. At a = 0.10, is there enough evidence to reject the claim that the proportions of those who accept free work for 10 or fewer clients are the same in each city?

How often do you go out dancing? This question was asked by a professional survey group on behalf of the National Arts Survey. A random sample of n, = 98 single men showed that r, = 24 went out dancing occasionally. Another random sample of n, = 91 single women showed that 18 went out dancing occasionally. Note: For degrees of freedom d.f. not in the Student's t table, use the closest d.f. that is smaller. In some situations, this choice of d.f. may increase the P-value a small amount and thereby produce a slightly more "conservative" answer. (b) Compute a 90% confidence interval for the population difference of proportions p, – p, of single men and single women who occasionally go out dancing.
