Answers are
A: 16.09 %
B: 0.65
C: Those who like Hamburgers but not burritos.
Step-by-step explanation:
Like Hamburgers ↓ Does Not Like Hamburgers↓ Total↓
Likes burritos → 39 38 77
Does not like burritos → 95 33 128
Total → 134 71 205
- So, according to the above table, a total of 77 customers like burritos, out of which 38 do not like hamburgers, hence, the remaining 39 like Hamburgers.
- A total of 128 customers do not like burritos, out of which 95 do like hamburgers, hence, the remaining 33 do not like Hamburgers.
- A total of 134 customers like hamburgers, but 71 do not like it, hence, the total respondents are 205.
Part A: The percent of respondents who do not like hamburgers and burritos both
There are 33 such respondents.
Hence, percentage 33/205 * 100 = 16.09%
Part B: Marginal relative frequency of all customers that like hamburgers
It will be the ratio of the sum of the customers that like hamburgers to the total number of respondents
Hence, ratio 134/205 = 0.65
Part C: The data point that has the strongest association of its two factors.
For this, we need to find the ratio of all the four data with the total.
Those who like Hamburgers and burritos: 39/134 = 0.29
Those who like Hamburgers but not burritos: 95/134 = 0.71
Those who like burritos but not Hamburgers: 38/71 = 0.53
Those who do not like burritos or Hamburgers: 33/71 = 0.47
So, the answer is those who like Hamburgers but not burritos.
