Hi there,

I am going through the “Statistics problems” section and found that the answers to the below question made sense. However, when going to the review section, it seems like only the mean average matters as the median is discarded. Can anyone please provide clarity on why this is?

Test question:

The following table indicates the number of paying customers at a local restaurant by week.

|Week number|Number of customers|

|1|23|

|2|67|

|3|198|

|4|13|

|5|x|

|6|100|

For what values of

xare both the mean and the median of paying customers for the entire six-week period between 70 and 80?

Indicate all that apply.

a. 70

b. 72

c. 74

d. 78

e. 81

f. 84
