Answer:
d. Yes, all of the expected counts are greater than or equal to 5
Step-by-step explanation:
Yes, the requirements satisfied to conduct a hypothesis test and all of the expected counts are greater than or equal to 5.
The <u>correct answer</u> is:
18.
Explanation:
There were 303 people surveyed total.
There were 64 people with brown eyes and black hair; that makes the percentage of the population 64/303 = 21.12% ≈ 21%.
There were 9 people with blue eyes and black hair; that makes the percentage of the population 9/303 = 2.97% ≈ 3%.
This means the percentage of students with brown eyes and black hair was greater than the percentage of students with blue eyes and black hair by:
21-3 = 18%.
