Question

A marketing firm is studying consumer preferences for winter fashions in four different months. From a population of women 18-21 years of age, a random sample of 100 women was selected in January. Another random sample of 100 women was selected in March. Another random sample of 100 women was selected in June. Another random sample of 100 women was selected in September. What is the number of samples?

Answer 1

There were total 4 samples collected and each sample had a sample size of n = 100.

Explanation:

We are given the following information in the question:

Collection of samples:

`1^(st)\text{ sample was done in January with a sample size n = 100}`

`2^(nd)\text{ sample was done in March with a sample size n = 100}`

`3^(rd)\text{ sample was done in June with a sample size n = 100}`

`4^(th)\text{ sample was done in September with a sample size n = 100}`

Hence, there were total 4 samples collected and each sample had a sample size of n = 100.
