A college professor is curious if the location of a seat in class affects grades in the class. They are teaching in a lecture hall with 240 students. The lecture hall has 10 rows, so they split the rows into 5 sections – Rows 1-2, Rows 3-4, Rows 5-6, Rows 7-8, and Rows 9-10. At the end of the course, they determine the top 25% of grades in the class, and if the location of the seat makes no difference, they would expect that these top 25% of students would be equally dispersed throughout the classroom. Their observations are recorded below. Run a Goodness of Fit test to determine whether or not location has an impact on the grade. Let α=0.05. Enter the expected count for each section in the table below. Rows 1-2 Rows 3-4 Rows 5-6 Rows 7-8 Rows 9-10 # in Top 25% Expected Counts Answer Key:12, 12, 12, 12, 12 Feedback: Top 25% of 240 is 240*.25 = 60, then divide this equally among the 5 groups. 60/5 Question 2 of 20 0.0/ 1.0 Points Click to see additional instructions A Driver’s Ed program is curious if the time of year has an impact on number of car accidents in the U.S. They assume that weather may have a significant impact on the ability of drivers to control their vehicles. They take a random sample of 150 car accidents and record the season each occurred in. They found that 27 occurred in the Spring, 39 in the Summer, 31 in the Fall, and 53 in the Winter. Can it be concluded at the 0.05 level of significance that car accidents are not equally distributed throughout the year? Enter the test statistic - round to 2 decimal places. Test statistic= Answer Key:10.53 Feedback: Spring Summer Fall Winter Observed Counts Expected Counts 150*.25 = 37.5 150*.25 = 37.5 150*.25 = 37.5 150*.25= 37.5 Test Stat = Question 3 of 201.0/ 1.0 Points Pamplona, Spain is the home of the festival of San Fermin – The Running of the Bulls. The town is in festival mode for a week and a half every year at the beginning of July. There is a running joke in the city, that Pamplona has a baby boom every April – 9 months after San Fermin. To test this claim, a resident takes a random sample of 300 birthdays from native residents and finds the following observed counts: January 25 February 25 March 27 April 26 May 21 June 26 July 22 August 27 September 21 October 26 November 28 December 26 At the 0.05 level of significance, can it be concluded that births in Pamplona are not equally distributed throughout the 12 months of the year? Hypotheses: H0: Births in Pamplona ______ equally distributed throughout the year. H1: Births in Pamplona ______ equally distributed throughout the year. Select the best fit choices that fit in the two blank spaces above. A. are, are not B. are not, are C. are, are
