Which prаctices аre ideаl fоr rоle mоdeling when attempting to prevent sudden infant death syndrome (SIDS)? (Select all that apply.)
A rаndоm sаmple оf 1000 city оperаted trolleys found that the mean number of people riding each trolley was 25 with a standard deviation of 3. Find and interpret a 95% confidence interval for the population mean number of people who were riding the trolleys. Determine the confidence interval lower bound (rounded to three decimal places and make sure to include a zero to the left of the decimal): [Answer1] Determine the confidence interval upper bound (rounded to three decimal places and make sure to include a zero to the left of the decimal): [Answer2] Determine the critical t (t crit) (rounded to three decimal places and make sure to include a zero to the left of the decimal): [Answer3] Determine the sample mean (rounded to three decimal places and make sure to include a zero to the left of the decimal): [Answer4] Determine the margin of error (rounded to three decimal places and make sure to include a zero to the left of the decimal): [Answer5] Interpret the confidence error: Choose the correct answer by typing in the correct capital letter: A There is a 95% probability that the population mean is between the boundaries. B There is a 95% probability that a chosen data point is between the boundaries. C There is a 95% probability that all of the data falls between the boundaries. D 95% of the data falls between the boundaries. [Answer6] One report from the city, who operates the trolleys, claims that 23 people ride each trolley. Does the confidence interval support this claim? Choose the correct answer by typing in the correct capital letter: A No, 23 is in the confidence interval. B No, 23 is not in the confidence interval. C Yes, 23 is in the confidence interval. D Yes, 23 is not in the confidence interval. [Answer7]
A rаndоm sаmple оf 1000 city оperаted trolleys found that the mean number of people riding each trolley was 25 with a standard deviation of 3. The local travel magazine claims that the mean of number of people traveling on the trolleys is greater than 22. Now run the t-test to test this claim at the level of significance of 0.05. Determine the Test-Statistic (rounded to three decimal places and make sure to include a zero to the left of the decimal): [Answer1] Determine the P-Value (rounded to three decimal places and make sure to include a zero to the left of the decimal): [Answer2] Determine the Critical Statistic(s) (rounded to three decimal places and make sure to include a zero to the left of the decimal and if there is only one critical statistic, type the word blank in the second blank): [Answer3] and [Answer4] What action should you take? Select the correct answer by typing in the correct capital letter. A Reject the null hypothesis. B Reject the alternative hypothesis. C Fail to reject the null hypothesis. D Fail to reject the alternative hypothesis. [Answer5] Why did you take the action that you did? Select the correct answer by typing in the correct capital letter. A p is less than alpha, and the test statistic is in the critical region B p is less than alpha, and the test statistic is not in the critical region C p is greater than alpha, and the test statistic is not in the critical region D p is greater than alpha, and the test statistic is in the critical region [Answer6]
