So your answer according to these hints I provided for you, should lead you to your answer, which should in other words be,
The 1st. The 2nd. And I would say...The 4th. The reason why I say not the 3rd one is because the 4 has nothing to do with the 8, the 3 does because it's divided by it.
If it's not useful, feel free to report for mistake in answer. -_-

Answer:
Here's how to reduce a fraction: Break down both the numerator (top number) and denominator (bottom number) into their prime factors. Cross out any common factors. Multiply the remaining numbers to get the reduced numerator and denominator.

Answer:
The value of the test statistic ![z = -0.6606](https://tex.z-dn.net/?f=z%20%3D%20-0.6606)
Step-by-step explanation:
From the question we are told that
The high dropout rate is
% ![= 0.061](https://tex.z-dn.net/?f=%3D%200.061)
The sample size is ![n = 1000](https://tex.z-dn.net/?f=n%20%3D%201000)
The number of dropouts ![x = 56](https://tex.z-dn.net/?f=x%20%3D%2056)
The probability of having a dropout in 1000 people ![\= x = \frac{56}{1000} = 0.056](https://tex.z-dn.net/?f=%5C%3D%20x%20%20%3D%20%5Cfrac%7B56%7D%7B1000%7D%20%20%3D%20%200.056)
Now setting up Test Hypothesis
Null ![H_o : p = 0.061](https://tex.z-dn.net/?f=H_o%20%3A%20%20p%20%3D%200.061)
Alternative
The Test statistics is mathematically represented as
![z = \frac{\= x - p}{\sqrt{\frac{p(1 -p)}{n} } }](https://tex.z-dn.net/?f=z%20%3D%20%5Cfrac%7B%5C%3D%20x%20-%20p%7D%7B%5Csqrt%7B%5Cfrac%7Bp%281%20-p%29%7D%7Bn%7D%20%7D%20%7D)
substituting values
![z = \frac{0.056 - 0.061}{\sqrt{\frac{0.061(1 -0.061)}{1000} } }](https://tex.z-dn.net/?f=z%20%3D%20%5Cfrac%7B0.056%20-%200.061%7D%7B%5Csqrt%7B%5Cfrac%7B0.061%281%20-0.061%29%7D%7B1000%7D%20%7D%20%7D)
![z = -0.6606](https://tex.z-dn.net/?f=z%20%3D%20-0.6606)
