Question

A junior analyst of a company has calculated the descriptive of the variable turnover (€) of the products, and has obtained: 74% percentile = € 1,123, Q3 = € 1,1250, 80% percentile = € 1,1250 and 81% percentile = € 1,252

a) You need to review the calculations, because it is impossible for Q3 and 80% percentile to coincide.

b) 74% of the products invoice more than € 1,123

c) Surely 19% of products invoice more than €1,252

d) There is a minimum of 5% of the products that invoice € 1,250

Answer 1

It is possible for Q3 and 80% percentile to coincide. when 75% of the products invoice less than € 1,250 and 20 % of the products invoice more than € 1,250. Thus a) is false.

74% of the products invoice less than € 1,123. So, b) is false.

81% of the products invoice less than €1,252. So,19% of products invoice more than €1,252 and c) is true.

As, Q3 and 80% percentile are equal to € 1,250, there is a minimum of 5% of the products that invoice € 1,250. So, d) is also true.
