Private Four-Year Colleges From the data in CollegeScores4yr we know that about 62% of four-year colleges in the US are private institutions. Suppose that we select samples of n - 75 schools at a time from the population of all four-year colleges and find the proportion of private schools in each sample, (a) Consider the distribution of these sample proportions when n - 75 and p-0.62. What is its form? Center - (round to three decimal places) Standard error
(b) What proportion of these samples will have less than 50% public schools? Round to three decimal places

yes

step-by-step explanation:

i dont know men

step-by-step explanation:

i would be happy to . most people on would also love to i'm sure. if you just want someone who has done algebra before and want a little more personal relationship than just begging strangers for , i can certainly be of service. i do have college myself so i might not be 24/7.

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
