Answer:
The proportion of former smokers with a university education is (A) 0.15
The proportion of men with a high school education that are current or former smokers is (B) 0.30
The degrees of freedom for the chi-square test for this two-way table are (B) 6
Step-by-step explanation:
The first thing to note is the two way table and ensure the proper arrangement of the figures in the table (Kindly find attached a picture of how the table should look)
Now, on to the first question on the former smokers with a university education = (43+28)/459 = 71/459 = 0.15 which is option A. [This is the total sum of former smokers with college and graduate school education].
The second question on the proportion of men with a high school education that are current or former smokers = (54+31+36)/459 = 0.285 = 0.30 (approximate value) which is option B.
The third question on the degrees of freedom for the chi-square test for this two-way table can be found with the formula DF = (r-1)(c-1) where,
DF = Degree of freedom ,
r = number of rows = 3
c = number of columns = 4 [<em>Kindly note that you have to exempt the row and columns with the totals</em>]
Therefore, DF = (3-1)(4-1) =2*3 = 6 which is option B.
