Answer 1

Answer:

¹22+++---555555555799999999

Answer 2

Given the sale of burgers in McDonalds, find its frequency distribution

Explanation:

1. since the maximum number of burgers is $31$ and minimum number of burgers is $25$. This can be divided into two classes.
2. the class intervals can be defined as $(24-27) (28-31)$ having class intervals $3$.
3. the frequency distribution is,                                                                                                   [tex]no.\ of\ burgers\ \ \ \ \ \ no.\ of\ days\\ (24-27)\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 10\\ (28-31)\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 6[/tex]              
4. the average units of burgers are given as,                                                               $mean=\frac{435}{16}= 27.18$      $->27\ burgers\ approximately$  
5. the mode of the burger produced is, $26$ and modal class is $(24-27)$.
