Answer:
Step-by-step explanation:
Put hypotheses as:
(Two tailed test at 4%)
Since population std deviation is given we can do Z test.
Test statistic t = mean diff/se = 
p value=0.075
Since p >0.04 our alpha, we accept null hypothesis.
At alphaequals0.04, we cannot reject the company's claim
What we have here are steps where each step requires twice as many blocks as the height of the steps. If you would like to check this math we can look at the staircase given:
3x2 + 2x2 + 1x2 = 6 + 4 + 2 = 12.
We can see that the math works, so now we can do the same work to find out how many steps 56 cubes can make.
6x2 + 5x2 + 4x2 + 3x2 + 2x2 + 1x2 = 42 (6 steps)
<span>7x2 + 6x2 + 5x2 + 4x2 + 3x2 + 2x2 + 1x2 = 56 (7 steps)

Therefore, the answer is B. 7 steps.
Answer:
Undefined. Or if you're talking about rise over run, horizontal is the run.
