Answer:
a) 0.5
Step-by-step explanation:
a)
Let T be the event that person uses trails daily and E be the event that person uses trails for exercise.
We have to find the probability that person uses the trails for exercise given that the person uses trails daily which can be denoted as P(E/T).
P(E/T)= P(E∩T)/P(T)
We are given that P(T)=0.24 and P(E∩T)=0.12. So,
P(E/T)= 0.12/0.24
P(E/T)= 0.5
Thus, the probability that person uses the trails for exercise given that the person uses trails daily is 50%

My answer to the problem is as follows:
<span>A lower standard deviation would mean that more of those scores are closer to the mean. The 3rd class mean is higher also, so you could conclude that the 3rd block class had more consistent higher scores than the first.

Z Test
Test Statistic, Ztest: -18.1912
Critical Zcritical: ±1.9607
P-Value: 0,0000
As Ztest is not within the limits of Zcritical we can reject the null hypothesis
