Chapter 8 Assignment (20 points) + Engvall's Commuting Times-Spring 2016/ Fall 2019 1. The first two columns in the table below represent the Professor Engvall's commuting times during 31 random days in Spring 2016 semester. (Column #1 -day; Column #2 - time in minutes). Next to that, you can see a similar table with the commuting time during 31 random days in Fall 2019 2. Use the data in these two tables to test the claim that the traffic got worse and the average commute time during the Fall 2019 is bigger than the average commute time during the Spring 2016 Use the 5-step Hypothesis Testing Procedure explained and practice in the Ch 8 materials to test the claim. Do not skip steps! It is your choice whether to use the formulas or the calculator and whether to use the Test Statistic or the P-value method. State a clear conclusion statement in the context of the problem. Hint: When stating the original claim and the Ho and Ha, use problem #20, pg 150 of the book. #20 is a part of your book homework. Find the difference between the mean time in Fall 2019 and Spring 2016. If the difference is positive, the mean time in Fall 2019 is bigger than the mean time in Spring 2016. If the difference is negative, the mean time in Fall 2019 is smaller than the mean time in Spring 2016. H 2019 > u 2016 is the same like u 2019 - u 2016 >0 (Ho) In step 3, for a sample to do the study, use the sample created by the differences of the corresponding elements of the given two samples. Then use the mean and st. deviation of this new sample to calculate the Test statistic in step 4. If you use a TI calc, you should enter this new sample into the calculator. Item # Fall 19 Spring16 Difference 63 60 61 62 -1 And so on... Note: This class does not cover a two sample studies!
