Asurvey showed that 79% of adults need correction (eyeglasses, contacts, surgery, etc.) for their eyesight. if 16 adults are randomly selected, find the probability that at least 15 of them need correction for their eyesight. is 15 a significantly high number of adults requiring eyesight correction?

0.121 is the probability that at least 15 of them need correction for their eyesight      

Step-by-step explanation:

We are given the following information:

We treat adult needing an correction as a success.

P(Adult need eye correction) = 79% = 0.79

Then the number of adults follows a binomial distribution, where

where n is the total number of observations, x is the number of success, p is the probability of success.

Now, we are given n = 16 and x = 15

We have to evaluate:

No, 15 is not a large number as the the probability for at least 15 adults to have eye correction is 12% approximately, which is not so small.

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

pretty sure 750 each month!
