A random sample of n = 16 scores is obtained from a parent population with σ = 12. If the sample mean is 6 points greater than the population mean, what is the z-score for the sample mean?

0.5

Step-by-step explanation:

Sample mean, x = 6 points greater than population mean ;

Population mean, m = 16

Standard deviation, s = 12

Zscore = (sample mean - population mean) / standard deviation

Zscore = (x - m) / s

x = 16 + 6 = 22

Zscore = (22 - 16) / 12

Zscore = 6 /12

Zscore = 0.5

this shows a reflection over the x-axis and is translated one unit down and 6 units to the right (x + 6, y - 1)

hope this !

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
