I'm working on a project that deals with the impact of age on helicopter pilots and want to see if that after age 40 accidents occur more frequently. I would like to use a T test to test this but an unsure how to go about doing it.
I think the hypothesis would be:
H1: Accidents occur more frequently above the age of 40.
H0: Number of accidents above age 40 are the same as below that age.
There are a total of 50 randomly selected accidents
The mean age is 48.12
The age standard deviation is
Age Range Frequency
Answer: we first calculate the mean and standard deviation of 50 data points.
Age Range Frequency Midpoint
24-31 5 (24+31)/2=27.5
32-39 8 (32+39)/2=35.5
40-46 8 (40+46)/2=43
The solution gives detailed steps on performing a hypothesis testing under t distribution with given data.
