Answer:
Step-by-step explanation:
subtract 34 from both sides
34 - 5(p - 1) - 34 = 4 - 34
simplify
-5 (p - 1) = -30
divide both sides by -5
-5 (p - 1) / -5 -30/-5
p = 7
Answer:
1)
The point estimate for the proportion of college graduates among women who work at home is 0.327
2)
The 80% confidence interval is given by (0.315; 0.339)
Step-by-step explanation:
For this case we have the following info given:
represent the women who worked at home who were college graduates
the sample size selected
Part 1
In order to find the proportion of college graduates among women who work at home and we can use the following formula:

The point estimate for the proportion of college graduates among women who work at home is 0.327
Part 2
Construct an 80% confidence interval for the proportion of women who work at home who are college graduates. Round the answer to three decimal places. An 80% confidence interval for the proportion of women who work at home Is < p <
The confidence interval for the true proportion would be given by this formula
For the 80% confidence interval the value for the significance is
and
, the critical value would be given by:
And replacing we goot:
The 80% confidence interval is given by (0.315; 0.339)
Y=5x-2 so you have to solve for x
Make y = 0
Then
Y=5x-2
+2. +2
2=5x
Divide by five
X= 2/5
Then
Y=5x-2
Put x into the equation
Y=5(2/5)-2
Y=2-2
Y=0
Done I hope that help (^∇^)
