Answer:
The probability that the difference of the proportions (industrial - rural) is greater than 0.2 is 0.7054
Step-by-step explanation:
Solution
Given that:
n₁ = 1500
x₁ = 800
p₁ =800/1500 =0.533
q₁ = 1- 0.533 = 0.467
Thus,
n₂ =1000
x₂ = 300
p₂ = 300/1000 = 0.3
q₂ = 1-0.3 =0.7
So,
p₁ - p₂ = 0.533 - 0.3
=0.233
Now,
SE (p₁ - p₂ ) =√0.533 * 0467/150 + 0.3 * 0.7/1000
=0.0613
So,
p ( p₁ - p₂ > 0.2
= p ( Ƶ > 0.2 - 0.233/0.0613
p = ( Ƶ > - 0.54)
= 0.7054
I’m not sure what kind of equation you want but if you want point slope it’s
Y+9=2(x-1) because the formula is y-y1=m(x-x1) so you just fill it in but if this isn’t the kind of answer you were looking for I wouldn’t mind helping you in the comments :)

Answer: 216 cupcakes can be made
Step-by-step explanation:
<u>Given information</u>
36 pounds of dough in total
⅙ pound of dough per cupcake
<u>Set variables</u>
Let x be the number of cupcakes that could be made
<u>Set equations from given information</u>
Total = unit × number
36 = (1/6) × x
<u>Multiply 6 on both sides to isolate [x] variable</u>
36 × 6 = (1/6) × x × 6
216 = 1 × x
Hope this helps!! :)
