Answer:
The test statistic Z = 3.125
Step-by-step explanation:
<em>Given Population proportion P = 0.25</em>
<em>Given sample size 'n' = 696</em>
<em>Sample proportion 'p⁻' = 0.30</em>
Test statistic
![Z = \frac{p^{-} -P}{\sqrt{\frac{P Q}{n} } }](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7Bp%5E%7B-%7D%20%20-P%7D%7B%5Csqrt%7B%5Cfrac%7BP%20Q%7D%7Bn%7D%20%7D%20%7D)
![Z = \frac{0.30-0.25}{\sqrt{\frac{0.25 X 0.75}{696} } } = 3.125](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7B0.30-0.25%7D%7B%5Csqrt%7B%5Cfrac%7B0.25%20X%200.75%7D%7B696%7D%20%7D%20%7D%20%20%3D%203.125)
<u><em>Final answer</em></u>:-
The test statistic Z = 3.125
Answer:
What is your question. Correct steps? If it is, then you did the steps correctly.
Answer:

Answer:
Step-by-step explanation:
Just give me the answer
You can read 100 pages in 5 hours.
40 pages in 2 hours. We need to get the unit rate. In this case, we need to get the number of pages read in 1 hour.
40 pages ÷ 2 hours = 20 pages per hour.
20 pages per hours * 5 hours = 100 pages.
