Hello from MrBillDoesMath!

Answer:

Discussion:

34 + 2x = 40 => subtract 34 from both sides

(34-34) + 2x = 40 - 34 => as (34-34) = 0 and 40-34 = 6

2x = 6 => divide both sides by 2

x = 6/2 = 3

Check the answer:

Does 34 + 2x = 40 if x = 3 ?

Does 34 + 2(3) = 40 ?

Does 34 + 6 = 40 ? YES! so the answer checks.

Thank you,

MrB

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
