Answer:
the mean of the sampling distribution for the proportion of supporters with sample size n = 165 is 0.5.
Step-by-step explanation:
According to the Central Limit Theorem, assuming the sampling is random and sample size is big enough (≥30) the mean of the sampling distribution is the population mean.
Therefore the mean of the sampling distribution for the proportion of supporters with sample size n = 165 is 0.5
-1^3 - -1^2 +1= -1. ...........
For this case we must express the number "423" in a radical way.
We have to, we can rewrite it as:
So, we have to:
By definition of properties of powers and roots we have:
So:
Answer:
41.803 is 42 rounded to the nearest whole number because when you go past .5 you round to the nearest highest number, but when your below .5 then you round to the nearest lowest number.
:) Well, I dunno about anyone else but this question makes my head spin!
