nd the P-value for the indicated hypothesis test. Also, use a 0.05 significance level and state the conclusion about the ill hypothesis (reject the null hypothesis or fail to reject the null hypothesis). 23) 23) In a sample of 88 children selected randomly from one town, it is found that 8 of them suffer from asthma. Find the P-value for a test of the claim that the proportion of all children in the town who suffer from asthma is equal to 11%. A) 0.5671; fail to reject the null hypothesis B) 0.0909; reject the null hypothesis C) 0.7165; fail to reject the null hypothesis D) 0.5671; reject the null hypothesis Find the value of the test statistic t. Assume that the simple random sample has been selected from a normally distributed population. 24) A large software company gives job applicants a test of programming ability. Twenty-five job 24) applicants are randomly selected from one large university and they produce a mean score of 183 and a standard deviation of 12. Use a 0.05 level of significance to test the claim that this sample comes from a population with a mean score greater than 160. A) 0.999 B) 9.583 C) 5.606 D) 1.121 Find the P-value for the indicated hypothesis test. Assume that the simple random sample has been selected from a normally distributed population. 25) Use a significance level of a = 0.01 to test the claim that M > 2.85. The sample data consist of 9 scores 25) for which x = 3.13 and s = 0.55. A) 0.9707 B) 1.5273 C) 0.0826 D) 0.1652 Formulate the indicated conclusion in nontechnical terms. Be sure to address the original claim. 26) Carter Motor Company claims that its new sedan, the Libra, will average more than 32 miles per 26) gallon in the city. Assuming that a hypothesis test of the claim has been conducted and that the conclusion is to reject the null hypothesis, state the conclusion in nontechnical terms. A) There is sufficient evidence to support the claim that the mean is greater than 32 miles per gallon. B) There is sufficient evidence to support the claim that the mean is less than 32 miles per gallon. C) There is not sufficient evidence to support the claim that the mean is less than 32 miles per gallon. D) There is not sufficient evidence to support the claim that the mean is greater than 32 miles per gallon. Find the value of the linear correlation coefficient r. 27) The paired data below consist of the temperatures on randomly chosen days and the amount a certain kind of plant grew (in millimeters): 27) Temp |62 76 50 51 71 46 51 44 79 Growth 36 39 50 13 33 33 17 6 16 A) -0.210 e employ B) 0.256 C ) 0 D) 0.196 the given data to find the equation of the regression line
