Step-by-step explanation:
A(-5,1) and B(0,4)
X1=0 , Y1=4 X2= -5 , Y2=1
y - 4 = ⅗(x-0) ==> y - 4 = ⅗ X ==> y = ⅗ X + 4
<u>C</u> is the answer
Answer:
And we can conclude at 95% of confidence that the true proportion of interest for this case is between 0.287 and 0.613
Step-by-step explanation:
The estimated proportion of interest is
We need to find a critical value for the confidence interval using the normla standard distributon. For this case we have 95% of confidence, then the significance level would be given by and . And the critical value is:
The confidence interval for the true population proportion is interest is given by this formula:
Replacing the values provided we got:
And we can conclude at 95% of confidence that the true proportion of interest for this case is between 0.287 and 0.613
