To calculate the percentage of males:
Total males = 180
Total respondents (excluding missing values) = 400 - 20 = 380
Percentage of males = (180/380) x 100 = 47.4%

To calculate the valid percentage of males:
Total males = 180
Total respondents (excluding missing values) = 400 - 20 - 20 (missing gender values) = 360
Valid percentage of males = (180/360) x 100 = 50%

Therefore, the correct choice is C.

In a Survey of 400 Respondents, 180 Indicated Their Gender
