The sample size is very large
Step-by-step explanation:
For Incorrect option we have,
When making the comparison between the sample proportion that is 0.201 and the hypothetical proportion that is 0.20. In this way it is possible to conclude that as the sample size increases, it also tends to normal. In this way it can be concluded that it is a non-aberrant sample. The sample proportion and the hypothetical proportion are almost equal.
For correct option we have that
So,
The sample size is greater than 30.
Here, sample size is very large . Hence difference is highly significant.
25=
[{50 divided by 5} plus 3]times 2 -1=25
To multiply a fraction with another fraction, we multiply the numerators the denominators:
