Question

Is the sample described a good sample? Explain. To find the average number of shoppers in a particular store, shoppers are counted on two consecutive Saturday mornings.

a) No; the sample is not selected from the population to be studied.
b) No; the sample is not random.
c) Yes; the sample is selected at random from the population to be studied.

Answer 1

The sample of shoppers counted on two consecutive Saturday mornings may not be random or representative of the typical store traffic, potentially leading to a biased understanding of the average number of shoppers.

Step-by-step explanation:

The sample described may not be indicative of the average number of shoppers in a particular store. By counting shoppers only on two consecutive Saturday mornings, the sampling might be biased, as weekends can attract more shoppers due to people being off work.

This sample is not truly random or necessarily representative of the typical foot traffic the store receives on different days of the week or at different times. A better sampling method would involve choosing different days of the week and various times to get a more accurate representation of the average number of shoppers.
