Answer: z equals 0.60 minus 0.72 all over the square root of the quantity 0.72 times 0.28 over 80
Step-by-step explanation:
let p be the population proportion of students complete their homework on a daily basis.
As per given , we have
p= 0.72
sample size : n= 80
Sample proportion :
Test statistic for proportion:
i.e.
i.e.
That is , z equals 0.60 minus 0.72 all over the square root of the quantity 0.72 times 0.28 over 80
First you want to subtract 36
so it looks like this
Then you want to cancel out the square root 4 by raising that to the 4th power (you must do this to both sides)
which is equal to
Then you take the cube root to both sides [tex]\sqrt[3]{(4x+164)^3}=\sqrt[3]{16777216}[tex]
Then you end up with the equation 4x+164=256
Then subtract 164 to both sides
4x=92
then divide 92 by 4
Then you get x=23
