In a sample of 50 museum visitors one afternoon, 22 were female and 28 were male. If there were 800 museum visitors that afternoon, estimate the number of visitors who were female.
220
352
448
700
To estimate the number of female visitors, we can use the ratio of female visitors to the total visitors in the sample and apply it to the total number of visitors in the afternoon.
The ratio of female visitors to total visitors in the sample is 22/50 = 0.44.
To estimate the number of female visitors in the afternoon, we can multiply the total number of visitors by the ratio of female visitors:
0.44 x 800 = 352
Therefore, we can estimate that there were 352 female visitors in the afternoon. Therefore, the answer is option B: 352.
