The y intercept is where the x value is zero
x=0 and y =4
The y intercept is (0,4)
3 times 7= 21 times three =63
Answer:
52.12
Step-by-step explanation
PEMDAS
Adding comes before subtracting

Using the z-distribution, it is found that the 90% confidence interval is given by: (0.6350, 0.6984).
<h3>What is a confidence interval of proportions?</h3>
A confidence interval of proportions is given by:

In which:
is the sample proportion.
In this problem, we have a 90% confidence level, hence
, z is the value of Z that has a p-value of
, so the critical value is z = 1.645.
The sample size and the estimate are given by:

Hence, the bounds of the interval are given by:


The 90% confidence interval is given by: (0.6350, 0.6984).
