Median is 18.

Mean is 22.

Step-by-step explanation:

Median has to be ordered from least to greatest:

1, 9, 17, 18, 25, 41, 43

then the median is the number in the middle, which is 18.

Mean is the sum of all the numbers, divided by 7 (because there are 7 numbers given)

25+18+9+1+43+17+41= 154

154/7 = 22

Median = 18 Mean = 22

Step-by-step explanation:

Let's sort the numbers in order to find the median:

1, 9, 17, 18, 25, 41, 43

The median is the middle number: 18

The mean or average is the sum of the data divided by the amount of items in the list. 1+9+17+18+25+41+43 = 154 so it is 154/7 = 22

So the mean is 22

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.
