a. 
D(22) = .197, p = .026 

b. 
D(22) = .026, p = .197 

c. 
D(22) = .086, p > .2 

d. 
D(22) = .2, p > .086 
2. Using the data from the table in Q1, what assumption can be made
regarding the distribution of the age data?
a. 
They are not normally distributed. 

b. 
They are normally distributed. 

c. 
It is unclear whether they are normally distributed or not. 

d. 
A Shapiro–Wilk test should be run to confirm the result. 
3.
Using the data in the table in Q1, split the data according to the sport. Run a Kolmogorov–Smirnov test on the diastolic blood pressure data. Which group’s data cannot assume a normal distribution?
a. 
Football 

b. 
Hockey 

c. 
Rugby 

d. 
All three are normally distributed. 
The value of the KS test statistic (D) is .19842.
The pvalue is .30943. Your data does not differ significantly from that which is normally distributed.
They are normally distributed.
3)
For Hockey
The value of the KS test statistic (D) is .24682.
The pvalue is .62858. Your data does not differ significantly from that which is normally distributed.
For Rugby
