m = -10
<u>y2 - y1</u>
x2 - x1
Answer: They are similar and congruent.
The are the same shape and size, just fliped diagonally.
H0: μ ≤ 34
H1: μ > 34
The z-test statistic is ≈ 1.8
The critical z-score is 1.28
we fail to reject the null hypothesis H0: μ ≤ 34
The z-test statistic is calculated using the formula:
then z= ≈ 0.18
The critical z-score is 1.28 for α=0.10 (one tailed)
Because the test statistic is less than the critical value, do not reject the null hypothesis.
