Answer:
The type of sampling method used is Stratified Sampling: Stratified Sampling is where the population has a number of distinct categories (different age groups in Billy's case). Here, the sampling frame can be organised into separate categories( age groups) which is called 'strata'. Each stratum is then sampled as an independent sub-population out of which individual elements can be randomly selected. In this case, each element in a group has a chance of being selected. With Stratified sampling, the best survey result occurs when elements within the strata are internally homogeneous ( in this case, the customers from each age group are selected).
Step-by-step explanation:
Set up a proportion.100 over 140 is = to x over 100. from there you cross multiply to get 10000=140x. then you divide both sides by 140 and get 71.42857143 and round it. if you are rounding to the nearest whole # it would be 71%
The answer would be C. :))
