(b) what is the most popular price range of the dinners?

a). Total dinner are 10

b). 15 - 45 is the most popular price of dinner.

Step-by-step explanation:

Given: Histogram

To find: a). Total dinners

             b). The most popular price range of the dinners  

We are given:

Prices of Dinners on X axis with width of 15 units and

Frequency on Y axis with Scale of 1 unit = 0.5

First we convert Histogram in Data of Tabular form,

Table is attached

Now from table,

a). Total dinner = 3 + 3 + 2 + 2

                         = 6 + 4

                        = 10

b). Since, 15 - 30 and 30 -45 has equal no of frequencies

    So, 15 - 45 is the most popular price of dinner.

Therefore, a). Total dinner are 10

                  b). 15 - 45 is the most popular price of dinner.
