Bot the owner of a sporting goods store randomly surveys 150 customers, of whom 95 are first-time customers. During the next week, the store has 900 customers. Based on the data from the survey, how many if the 900 customers can the store owner expect to be first-time customers?

Answer 1

To find out how many of the 900 customers can be expected to be first-time customers, we need to determine the proportion of first-time customers from the survey.

The proportion of first-time customers from the survey is given by: 95/150 = 0.6333 (rounded to 4 decimal places).

Now, we can use this proportion to estimate the number of first-time customers among the 900 total customers. Multiply the proportion by the total number of customers:

0.6333 * 900 = 569.97

Rounding to the nearest whole number, the store owner can expect approximately 570 first-time customers out of the 900 total customers.
