Answer:
Step-by-step explanation:
Sample proportion p is the proportion of favourable numbers to total number in the sample
By central limit theorem and also approximation of binomial to normal , we have sample proportion for large number of samples will be normal
with mean = sample proportion
and std deviation =
Thus we find standard deviation of proportion sample is inversely proportional to the square of the sample size n.
It follows automatically that as sample size increases std deviation decreases.
Here from 80 sample size was made to 200
So std deviation would decrease automatically
Answer:
13.31 x
Step-by-step explanation:
So, if we take the two equations, and add the normal numbers together, we have: 5.97 + 7.34 = 13.31
Then if we add the two tens together it would be: +
= 10 to the power of 46.
The equation would be 13.31 x
