Answer 1

B. 108 calories

Explanation:

The mean number of a data set is

`\text{Mean}=\frac{\text{The sum of all calories in products}}{\text{The number of products}}`

Corn chips: 230 calories

Popcorn: 25 calories

Potato chips: 115 calories

Pretzels: 62 calories

Thus,

The sum of all calories
`=230+25+115+62=432`

The number of productrs = 4

The mean number of calories
`=(432)/(4)=108`
