Notice that our sample needs to be restricted to exclusively women, so we need to add all women responses to have the total of women iterviewed:
Total of our set:
67 + 73 + 11 + 1 + 3 + 13 + 42 + 51 = 261
Now the number of successes (woman selected to prefer to shop at Belk) is: 42
Therefore the propability is the quotient of 42 / 261 = 0.1609195
which is the decimal form of the percent: 16.09195%
which rounded to the nearest hundredth of the percent gives:
16.09%
