Research suggests that about 60% of CSU graduates started at a community college. In random samples of 100 CSU graduates, the percentage who started at a community college varies. What is the probability that in a random sample of 100 CSU graduates the error is within 5% of the population proportion of 60%

80 the answer is 80

step-by-step explanation:

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
