Answer 1

(a) Average sales per store = Total Sales per chain / Total number of stores

= (149 * 7231) + (74 * 3585) + (361 * 505) + (59 * 3238) / (149 + 74 + 361 + 59)

= 1716056 / 643 = 2668.827   $\approx$ $ 2669

(b) To find the median salary, we arrange the salaries in ascending order and create the cumulative frequency table as shown

Sales	505	3238	3585	7231
Stores	361	59	74	149
CF	361	420	494	643

Sine the total number of stores is 643, the median will be = (643 + 1) / 2 = 322nd store. The 322nd store has a sales value of 505 as seen in the table.

Therefore the median sales = $ 505

(c) Average sales / chain = (Sales / Store * number of stores) / Total number of chains

= (149 * 7231) + (74 * 3585) + (361 * 505) + (59 * 3238) / 4

= 1716056 / 4 = $ 429014
