We can use the proportion of people carrying bags from the sample of 50 people to estimate the number of visitors who purchased something out of the total 4,800 visitors to the mall.

The proportion of people carrying bags in the sample is:

37/50 = 0.74

This means that 74% of the sample of 50 people were carrying bags.

To estimate the number of visitors who purchased something out of the total 4,800 visitors, we can multiply the proportion by the total number of visitors:

0.74 x 4,800 = 3,552

Therefore, we can predict that approximately 3,552 visitors out of the total 4,800 visitors purchased something on that day.
