Answer:
We are given:
Confidence level = 99%. Therefore, the critical value at 0.01 significance level using the standard normal table is given below:
Margin of error is given in the question as:
Since the previous proportion is not given, therefore, we need to assume 
Therefore, the sample size is:
Therefore, 664 sample observations are required.

Answer:
We have a + b as;
2 + 3 = 5
Step-by-step explanation:
Here, we want go get the value of a and b
from the second equation, we can get an expression for b
We have this as;
7a - b = 11
Thus,
b = 7a - 11
Now, from here, we can substitute the value of b into the first equation
We have this as;
5a + 4(7a - 11) = 22
5a + 28a -44 = 22
33a = 22 + 44
33a = 66
a = 66/33
a = 2
Recall;
b = 7a - 11
substituting the value of a from above;
b = 7(2) - 11
b = 14 - 11
b = 3
