I'm not 100 percent sure but I think is e

**Answer: They are similar and congruent.**

**Step-by-step explanation:**

The are the same shape and size, just fliped diagonally.

**Answer:**

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

**Step-by-step explanation:**

H0: μ ≤ 34

H1: μ > 34

The z-test statistic is calculated using the formula:

z= where

- X is the average class size found in the sample (35.6)
- M is the mean according to the null hypothesis (34)
- s is the standard deviation for class size (9)

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.
