On a test that has a normal distribution, a score of 60 falls two standard deviations above the mean, and a score of 42 falls on

Sergeu [11.5K]

Answer:

Step-by-step explanation:

Given that:

$A \ score \ of \ 60 \ falls \ two \ standard \ deviations \ above \ the \ mean \\ \\ A \ score \ of \ 42 \ falls \ one \ standard \ deviation \ below \ the \ m ean$

The interval for score = 60 - 42 = 18

If we divide it by the 3 standard deviations; the interval result into

= 18/3

= 6

So, the standard deviation is 6, and the mean = 42 + 6

= 48
