men and women in the sample

In this problem, the level of significance is:
A. 150 total people in the sample.
B. $80,000, the maximum income value.
C. 60 and 90, the total number of men and women in the sample, respectively.
D. 0.05, the highest probability/chance that you are willing to risk of incorrectly rejecting the null hypothesis.
E. (# of rows - 1)(# of columns - 1) = (2 - 1)(3 - 1) = (1)(2) = 2 degrees of freedom (df)
I lean towards D is that correct?.A sample of 150 individuals (males and females) was surveyed, and the individuals were asked to indicate their yearly incomes. The results of the survey are shown below.

 

 

Income Category Male Female   

Category 1: $20,000 up to $40,000 10 30   

Category 2: $40,000 up to $60,000 35 15   

Category 3: $60,000 up to $80,000 15 45  

 

Test at α = 0.05 to determine if the yearly income is independent of the gender.
