Question

A food truck did a daily survey of customers to find their food preferences. The data is partially entered in the frequency table. Complete the table to analyze the data and answer the questions:


Part A: What percentage of the survey respondents liked hamburgers but do not like burritos? Show all work. (3 points)

Part B: What is the marginal relative frequency of all customers who like hamburgers? Show all work. (3 points)

Part C: Which category has the lowest joint relative frequency? Show all work. (4 points)

Answer 1

HELP!!! PLEASE!!!

Answer 2

Oh. For this one, you first have to fill out the chart. Are you able to do that with the information you've been given?

Answer 3

yes

Answer 4

You already have the answer to part A. 95 people out of... 205. 95/205 is 0.46 which that would translate to 41%.

Answer 5

46%, my bad.

Answer 6

Just a side note, I have a terrible migraine and I'm sick with a cold, so if I mess some calculations up, feel free to correct me.

Answer 7

so basically
Part A-) 0.46
Part B- is 46%
How about part c?

Answer 8

Ok perfect and for part b and c sorry for the bother!

Answer 9

No, it's not a bother at all!
And part B, when I looked it up, Marginal Relative Frequency is, quoted from study.com, "the ratio between the frequency of a row total or column total to the total frequency of the data"

Answer 10

so it will be 134?

Answer 11

If I did this correctly, the total number of people who liked hamburgers is 134 and the total amount of people is 205.

Answer 12

You have to find the ratio of 134:205

Answer 13

Or written in another way, 134 of 205, I believe.

Answer 14

So you divide 134/205 to find the answer to part B.

Answer 15

0.65?

Answer 16

Which is what as a percentage?

Answer 17

65% ?

Answer 18

Correct. The exact answer you would put is 65.37%, but we'll keep it as 65% for a simpler answer.

Answer 19

perfect!

Answer 20

Part C is the simplest out of all of them.

All you do is take each of the earlier numbers; 39,38,95, and 33 and divide all of those by 205.

Answer 21

So 39/205
38/205
95/205
33/205

Answer 22

Once you calculate all of those and you find the lowest percentage, that's your answer to part C.

Answer 23

33/205 is the lowest because it gave me 0.16

Answer 24

Then the answer is 16% and that's the answer to Part C.

Answer 25

To recap,
Part A is 46%
Part B is 65% (65.37%)
Part C is 16%
