Agreenhouse in a? tri-county area has kept track of its customers for the last several years and has determined that? 28% of its customers plant a vegetable garden in the spring. the greenhouse obtains a random sample of 1000 of its customers. what is the mean of the sampling distribution of modifyingabove p with caretp? , the sample proportion of customers that plant a vegetable garden in the? spring?

The mean is 280 customers.

The sample proportion is 28%.

Explanation:

For each customer, there are only two possible outcomes. Either they plant a vegetable in the spring, or they do not. This means that we can solve this problem using concepts of the binomial probability distribution.

Binomial probability distribution.

Probability of exactly x sucesses on n repeated trials, with p probability. Has an expected value of:

In this problem, we have that:

There are 1000 customers, so .

28% of its customers plant a vegetable garden in the spring. This means that .

So:

What is the mean of the sampling distribution of modifyingabove p with caretp?

The mean is the expected value, so:

The mean is 280 customers.

The sample proportion of customers that plant a vegetable garden in the? spring?

It is the same as the population proportion, so the sample proportion is 28%.

start by isolating the variable on one side by adding 43w^2 to both sides.   the equation will read:

25w^2+5=0

*subtract 5 from both sides*

25w^2=-5

*divide both sides by 25*

w^2=-1/5

*take the square root of both sides*

w=√(-1/5)

the square root of -1 is i.   the square root of 5 remains √5

the answer is i/√5.

hope this

so i don't know what video you're talking about, but here's some stuff steve jobs gave as advice.

- love what you do.

- the worst thing that could happen might turn out to be the best thing that could happen.

- follow your heart and trust it knows where it's going.
