Explanation / Answer
1) Testing 50 people in a driving simulator to find the average reaction time to hit the brakes when an object is seen in the view ahead.
Ans: Statistical Test
Here we are talking about average reaction time.
and one more thing is that the hypothesis like
H0: The average reaction time to hit the brakes when an object is not seen in the view ahead
HA: The average reaction time to hit the brakes when an object is seen in the view ahead
2) Giving a Coke/Pepsi taste test to random people in NYC to determine if there is evidence for the claim that Pepsi is preferred.
Ans: Statistical Test
Here we can apply statistical test because, they are claming that the "Is there any evidence of the claim that Pepsi is prefered"
We can set hypothesis like,
H0: There is not evidence that Pepsi is prefered
HA: There is evidence that Pepsi is prefered
3) A sample of 50 cans of tomatoes are tested for levels of the chemical BPA to see if there is evidence that the mean level is greater than 100 ppb.
Ans: Statistical Test
Here we can apply statistical test because, they are claming that the "Is there is evidence that the mean level is greater than 100 ppb"
We can set hypothesis like,
H0: There is evidence that the mean level is not greater than 100 ppb
HA: There is evidence that the mean level is greater than 100 ppb
4) Testing to see if colonoscopy provides evidence to save lives. (Choose One)
Ans: Statistical Test
Because they are going to test "If colonoscopy provides evidence to save lives or not save lives"
the hypothesis will be like
H0: The colonoscopy doesn't provides evidence to save lives
HA: The colonoscopy provides evidence to save lives
