I believe the answer is 4
Answer:2
2/1=2
I hope this is good enough:
Let's review the terminology. A product is what you get when you multiply two numbers. So, the product of 5 and 2 is basically "5*2," and the product of 5 and 1 is "5*1."
The difference means when you subtract one from the other. So, the difference of 5*2 and 5*1 means "(5*2)-(5*1)". (Note: I put in parentheses to make sure the reader understands that 5*2 is separate from 5*1. 5*2-5*1 is confusing: you might not know what to do first!)
So, "(5*2)-(5*1)" can be your answer, OR you can simplify it further by actually doing the multiplication: "10-5". If you want the answer, just subtract--the expression is equal to 5.
Answer: "<span>(5*2)-(5*1)" OR "10-5" OR "5"</span>

Answer:
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
