Use the given data to find the minimum sample size required to estimate the population proportion. 19) Margin of error: 0.04; confidence level: 99%; from a prior study, p is estimated by 0.07. 19) A) 156 B) 270 C) 11 D) 324 Assume that a sample is used to estimate a population mean u. Use the given confidence level and sample data to find the margin of error. Assume that the sample is a simple random sample and the population has a normal distribution. Round your answer to one more decimal place than the sample standard deviation. 20) 99% confidence; n = 201; x = 200; s = 56 20) A) 9.3 B) 10.3 C) 7.8 D) 12.5 Express the null hypothesis and the alternative hypothesis in symbolic form. Use the correct symbol (u, p, o) for the indicated parameter. 21) The owner of a football team claims that the average attendance at games is over 80,300, and he is 21) therefore justified in moving the team to a city with a larger stadium. A) HO: M > 80,300 B) HO: M = 80,300 C) HO: H 80,300 For Problems 23-25 show your work. Use the given data to find the equation of the regression line. Round the final values to three significant digits, if necessary. 22) x 1.2 1.4 1.6 1.8 2.0 22) y 54 53 55 54 56 A) y = 54 B) y = 55.3 + 2.40x C) y = 50.4 + 2.50x D) y = 50 + 3x For Problems 23-25 show your work. Use the given degree of confidence and sample data to construct a confidence interval for the population mean u. Assume that the population has a normal distribution. 23) A sociologist develops a test to measure attitudes towards public transportation, and 27 randomly selected subjects are given the test. Their mean score is 76.2 and their standard deviation is 21.4. Construct the 95% confidence interval for the mean score of all such subjects
