BAD 376 PROBLEM ANALYSIS: THE CHI-SQUARE FOR GOODNESS OF FIT QUESTION 1 Use Chi-Square-table and find the following: 1. % if the degrees of freedom = 8; and a= 1%. 2. % if the degrees of freedom = 12; and a 5%. 3. 4. if the degrees of freedom = 20; and a= 10%. if the degrees of freedom 24; and a= 2.5%. = QUESTION 2 A regional transit authority is concerned about the number of riders on one of its bus routes. In setting up the route, the assumption is that the number of riders is the same on every day from Monday through Friday. A random sample of 90 riders yielded the following results: Day Monday Tuesday Wednesday Thursday Friday Number of Riders 13 16 28 17 16 Using a =10%, determine whether the transit authority's assumption is correct. Hint: If the null hypothesis is true then the number of riders is the same on every day from Monday through Friday. So, the proportions of riders on Mondays, on Tuesdays, on Wednesdays, on Thursdays or on Fridays will be the same. Let P1, P2, P3, P4 and P5 be the proportions of riders on Mondays, on Tuesdays, on Wednesdays, on Thursdays or on Fridays, respectively. Because there are five alternatives (Mondays, Tuesdays, Wednesdays, Thursdays and Fridays), it follows that P₁ = P₂ = P₁ = P₁ = P 1 = 0.20
