Answer:
The mean is given by:
And the deviation:
Step-by-step explanation:
For this case we assume that the true population proportion of Americans do not know that GOP stands for Grand Old Party is 0.55 and we select a random sample of n = 953 americans
For this case we assume that we satisfy the conditions to use the normal approximation for
1) np >10 , n(1-p)>10
2) Independence
3) Random sample
4) The sample size is less than 10% of the population size
We assume that all the conditions are satisfied and the distribution for would be:
The mean is given by:
And the deviation:
Answer:
Example: 5(3x + 8)
= 5(3x) + 5(8)
