I am getting problems with my calculations. For the first part of the question I got 68 when I try another calculation I got 1. One of the method used was Degree of freedom =(r1)(c1).
TABLE 127
The director of transportation of a large company is interested in the usage of her van pool. She considers her routes to be divided into local and nonlocal. She is particularly interested in learning if there is a difference in the proportion of males and females who use the local routes. She takes a sample of a day's riders and finds the following:
Male Female Total
Local 27 44 71
NonLocal 33 25 58
Total 60 69 129
She will use this information to perform a chisquare hypothesis test using a level of significance of 0.05.
(a) Referring to Table 127, the test will involve ________ degree(s) of freedom.
A) 1
