100 POINTS AND BRAINLIEST TO CORRECT ANSWER: AP STATISTICS

You know that a certain trait occurs in 30% of the population. You want to know how many individuals you must draw from the population, on average, to get three subjects with the trait.
A. Describe how you would use a table of random numbers to do a simulation of this situation. (11 points)

B. Use the table of random numbers below to carry out five repetitions in the simulation method you described in (A) above. Mark the table so that it's clear to the reader how you did the simulation. Begin with the first element of the first row. If it's necessary to continue past the first row, start at the beginning of each row. Based on your five simulations, what's your best guess as to the number of trials required to achieve three successes? (11 points)

correct choice is a

step-by-step explanation:

the equation of the line passing through the points and is

thus, the equation of the line that passes through the points (0, -6) and (-3, 0) is

answer is c

step-by-step explanation:

81/12=324/x

x=48

irst, find the z score of a score of 80. this is given by the formula z = (x-u)/o, where x is the score, u is the mean, and o is the standard deviation. this gives

z = (80-78)/12 = 1/6 = .1667

now, find what percentile a z score of 1/6 correlates to in the normal distribution.

a z score of 1/6 = .1667 is equivalent to the 56.36th percentile of the distribution. so the probability a score is over this is 1-.5636 = .4364

the mean of a sample mean is equal to the original mean. however, the standard deviation of a sample mean is equal to the original standard deviation divided by the square root of n (sample size). so the new standard deviation is 12/sqrt(16) = 3.

the new z score is 80-78/3 = 2/3 = .667. this is equivalent to the 74.86th percentile. so the probability that the mean will be greater than this score is 1-.7486 = .2514.

35/2 is it i think maybe
