Which of these tables represents a non-linear function? a 2-column table with 4 rows. column 1 is labeled x with entries 17, 18, 19, 20. column 2 is labeled y with entries 20, 19, 18, 17. a 2-column table with 4 rows. column 1 is labeled x with entries 17, 18, 19, 20. column 2 is labeled y with entries negative 16, negative 17, negative 18, negative 19. a 2-column table with 4 rows. column 1 is labeled x with entries 17, 18, 19, 20. column 2 is labeled y with entries 16, 17, 19, 20. a 2-column table with 4 rows. column 1 is labeled x with entries 17, 18, 19, 20. column 2 is labeled y with entries negative 20, negative 19, negative 18, negative 17.

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.

what do you mean

have a great day

$25 becasue a 10 increase would make it from 80 to 50
