A random experiment involves drawing a sample of 12 data values from a normally distributed population.

20	29	39	42
43	45	45	46
47	54	55	59

Calculate the z-score of the median of the data set.

z = (Round to 3 decimal places)

Hint: You will need the mean and standard deviation first. Round your mean and standard deviation calculations to 5 decimal places.

Answer 1

Answer #1

solution:-

given data = 20,29,39,42,43,45,45,46,47,54,55,59

mean = 43.66667

standard deviation = 10.83205

median = 45

so,

here we have to assume median as x

=> z-score = (x-mean)/standard deviation

=> z-score = (45-43.66667)/10.83205

=> z-score = 0.123
