Answer:
The width of the 95% confidence interval for p is 0.2496
Step-by-step explanation:
Taking into account that the proportion of the students from the sample that prefer the taste of fresh-brewed coffee is calculated as:
p' = 35/60 = 0.5833
Because there are 60 students in the sample and 35 prefer the taste of fresh brewed coffee.
So, the width of the 95% confidence interval for p is calculated as:
Where n is the number of the students in the sample and 1.96 is the z values that satisfy that:
2P(Z>1.96) = 1 - 0.95 = 0.05
Then, replacing p' by 0.5833 and n by 60, we get:
Finally, the width of the 95% confidence interval for p is 0.2496

A. 1 to the right and 2 up from zero 1,2
B.1 to the left and two up from zero -1,2
C. 11 to the left and 2 up from zero -11,2
D. 11 to the right and 2 up from zero 11,2
Answer:
Well, y = 2x - 3.
Step 1:
Subtract 2x from both sides.
-y = -2x + 3.
Step 2:
Divide it all by negative 1.
y = 2x - 3.
IF YOU WANT TO SOLVE FOR X:
Well, x = .5y + 3/2
Which equals to:
(y + 3)/2.
Step 1:
Add y to both sides.
2x = y + 3.
Step 2:
Divide it all by 2:
x = .5y + 3/2
Which equals to:
(y + 3)/2.
They are the same.
Hey there!
In order to find the amount that Sue paid for the shirt, all you have to do is subtract the price of the jeans from the total amount that she paid for the jeans and the shirt.
55.75 – 25.25 = 30.5
Sue paid $30.50 for the shirt, making your answer A.
Hope this helped you out! :-)
