- you are conducting a study to see if the average female life expectancy is significantly different from 99. Your sample data (n=13) produce the test statistic t=-2.87. Find the p-value accurate to 4 decimal places. You are conducting a study to see if the probability of catching the flu this year is significantly more than 0.28. Your sample data produce the test statistic z=1.64. Find the p-value accurate to 4 decimal places. You are conducting a study to see if the accuracy rate for fingerprint identification is significantly less than 0.1. Your sample data produce the test statistic z=-1.747 . Find the p-value accurate to 4 decimal places.A recent newspaper article claims that 62% of car accidents involve some evidence of distracted driving. A police officer questions this claim, and pulls a random sample of 61 accident reports. If 43 of them involve distracted driving, is this enough evidence to show that the proportion of car accidents involve some evidence of distracted driving is significantly greater than than reported by the newspaper? (Use α=0.025) The test statistic = (please show your answer to 3 decimal places.) The p-value = (Please show your answer to 4 decimal places.)Sixty teachers were interviewed regarding their opinion on the issue of increasing the number of years of basic education from 10 to 12years. Do these teachers differ significantly in their opinion on this issue? Test the claim at α=0.05. Agree – 32, Disagree – 10, Undecided – 18 What is the tabulated value and the statistical value?
- Studies show that the level of anxiety has changed since the pandemic. The average score before the pandemic was mu equal to 36. A sample of 20 individuals surveyed in the past two weeks produced M=37.6 and s=9.8. Based on the sample, was there a significant difference in the average anxiety level since the pandemic started at the 5% significance level? What is the positive critical value? (a)2.093 (b)2.086 (c)1.729 (d)1.725A researcher wishes to see if there is a difference in the manual dexterity of athletes and that of band members. Two random samples of 30 are selectedfrom each group and are given a manual dexterity test. The mean of the athletes’ test was 87, and the mean of the band members’ test was 92. The population standard deviation for the test is 7.2. At α = 0.01, is there a significant difference in the mean scores?A researcher conducted a Chi-square test to determine whether the progeny of oyster mushroom follows the ratio of 3 grey: 1 white. From his calculation, he found his calculated Chi-square is smaller than the critical Chi-square value from the table. Which one is the CORRECT conclusion? a. Null hypothesis cannot be rejected. The progeny ratio is different than the expected ratio. b. Null hypothesis is rejected. The progeny ratio follows the expected ratio. c. The ratio of the progeny from his experiment does not follow the ratio 3:1. d. The ratio of the progeny from his experiment is consistent with the ratio 3:1.
