a. Show the sampling distribution of p, the proportion of groceries thrown out by your sample respondents.b. What is the probabi
Anika [276]

Answer:

The corresponding p - value will be  is < 0.00001 which is less than 0.05

Step-by-step explanation:

Suppose p= 0.12 and n= 540 then the standard deviation can be taken out as √p(1-p)/n= √0.12(1-0.12)/540= 0.014

For the probability that the survey will provide a sample proportion within 6.03 of the population proportion

we will find the z statistic

z= p^-p/√p(1-p)/n

But √p(1-p)/n= 0.014 and p^-p= 6.03

Putting the values

z= 6.03/0.014= 430.71

The corresponding p - value will be  is < 0.00001 which is less than 0.05

A= 5 + 2 = 7
You get this by doing the inverse operation so minus 2 by 2 and 7 then you get your answer so it should look like this
X+2= 7
-2. -2
———
X= 5

B: 15-4=11
+4. +4
————-
X= 15

C: 4(3) = 12

D: 50/5 = 10

Btw this should be easy, try doing it on to your own now.
