Answer 1

Step-by-step explanation:

Given;

We are given a frequency table which displays a survey of numbers of customers that like hamburgers and burritos and those that do not like hamburgers and burritos.

Required;

We are required to analyze the table and use the values to answer the questions that follow.

Solution;

We shall begin by completing the table as follows;

Part A:

What percentage of the survey respondents do not like both burritos and hamburgers?

The percentage that do not like hamburgers is

`Does\text{ }not\text{ }like\text{ }hamburgers=(95)/(205)`

The percentage that do not like burritos is

`Does\text{ }not\text{ }like\text{ }burritos=(135)/(205)`

The percentage that does not like both burritos and hamburgers is;

`(54)/(205)=0.263414634146`

Expressed as a percentage, this is

`\begin{gathered} Percentage=0.263414634146*100 \\ \\ Percentage=26.3414634146 \\ \\ Percentage=26.34\%\text{ }(rounded\text{ }to\text{ }the\text{ }nearest\text{ }hundredth) \end{gathered}`

The marginal relative frequency of all customers that like hamburgers is the total of all hamburger lovers divided by the total of all respondents.

`\begin{gathered} Marginal\text{ }relative\text{ }frequency=\frac{hamburger\text{ }lovers}{total\text{ }respondents}=(110)/(205) \\ \\ Marginal\text{ }relative\text{ }frequency=0.536585365854 \\ \\ Marginal\text{ }relative\text{ }frequency=53.66\%\text{ }(rounded\text{ }to\text{ }2\text{ }decimal\text{ }places) \end{gathered}`

ANSWER:

Part (a) 26.34%

Part (b) 53.66%
