Stattles candies have five different colors that are equally distributed (20% orange), and each bag represents a random sample of the entire population of Stattles. A 14 ounce bag of Stattles has 220 of the multi-colored
candies.
a. Cindy loves orange Stattles and is interested in exploring how many orange Stattles she can expect to get in
a bag. Demonstrate that the sampling distribution of p, the proportion of orange Stattles in a bag, satisfies all
three conditions of inference.
b. Find the mean and standard deviation of the sampling distribution of p.
c. Sketch and label the sampling distribution curve using your values from part b.
d. Calculate the probability that Cindy will get at least 50 orange Stattles in her next 14 ounce bag.

step-by-step explanation:

yes

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1
