Answer: 14.29 shops
Explanation:
Total number of shops:
= 30 + 28 +16 + 14 + 10 + 7 + 3
= 108 shops
Median position = 108/2 = 54
Median is in range where cumulative number of shops is 54.
Range is: More than or equal to 10
Median = Lower limit of median range + range of median range * (median position - cumulative frequency up to median range) / frequency of median range
= 10 + 5 * (108/2 - 30) / 28
= 10 + 4.29
= 14.29 shops
