Test statistics of <u>1.455 </u>
P-value = 0.0728
Step-by-step explanation:
From the given information:
The test statistics can be computed as:
Z = 1.455
We want to test if the customer satisfaction increased significantly(one-tailed test)
Null hypothesis:
Alternative hypothesis:
P-value = P(Z>1.455)
= 0.0728
b) Type II error implies the error of accepting when
is true.
This implies inferring that there is no huge improvement in passenger's satisfaction when there is.
c) Type 1 and Type II errors are inversely proportional. In this situation, as one increases, the other definitely decreases.
∴ A Smaller value of Type II error will be achieved by a higher type I error.
⇒ 0.10
