Answer:
- A = 1.5
- B = -1/3
- C = -4/3
Step-by-step explanation:
For A:
- A is smack in the middle of 1 and 2, so it it 1 1/2 or 1.5 (same thing)
For B:
- Each tick mark between the numbers represents 1/3
- B is on the first tick mark between 0 and -1, so therefore it is -1/3
For C:
- C is on the first tick mark between -1 and -2
- That means C is -1 1/3
- -1 1/3 = -4/3
I hope this helps!
The question requires that we have to state the hypothesis:
null hypothesis;H0: u1 < u2, the alternate hypothesis;H1: u1 > u2. The one tail test is what is to be used.
<h3>A.
How to state the hypothesis</h3>
H0: u1 < u2
H1: u1 > u2
The one tail test statistic is what is to be used here
<h3>B.
standard error </h3>

= 1.49
The df = 17 + 15 - 2
= 30
test statistic = 18.9 - 17.4 / 1.49
= 1.007
We have the critical value on excel as T.INV(0.9,30)
= 1.310
E. At 0.1, we can conclude that t-value (1.007) does not lies in the rejection area. We fail to reject the null hypothesis. Hence we conclude that the mean vacation with the unlimited plan is greater.
