Answer:
a) The level of significance is large because here z is not appropriate.
b) The true critical value is larger than z because the level of significance is large.
Step-by-step explanation:
a) Based on the question under consideration, the true level of significance is larger than .05 level of significance is large, the reason being that z is not appropriate in this case.
b) The true critical value is larger than that of the critical z, this is because the level of significance is large.
t* in P(T > t*) = 0.975 is more than z* = 1.96 in P(z> z*) =0.975

Wait, what? Why did I reverse the direction of the greater than sign to a less than sign? Well, when you divide a negative number in an inequality problem, you need to reverse the sign. I hope the actual solving is obvious. If it's not, just ask for clarification!
Answer:
0.4167 is the probability that a person bought a truck given it is a hybrid vehicle.
Step-by-step explanation:
We are given the following in the question:
V: Event of buying a hybrid vehicle.
P(V) =12% = 0.12
T: Event a truck is bought.
We have to find the probability that a person bought a truck given that it is a hybrid vehicle.
Thus, 0.4167 is the probability that a person bought a truck given it is a hybrid vehicle.
