Step-by-step explanation:
The z score is a score used to determine the number of standard deviations by which the raw score is above or below the mean, it is given by the equation:

Given that μ = 650, σ = 50. To find the probability that 5 students who have a mean of 490, we use:

From the normal distribution table, P(x < 490) = P(Z < -7.16) = 0.0001 = 0.01%
Since only a small percentage of people score about 490, hence the local newspaper editor should write a scathing editorial about favoritism
X = y - 5
x = 1 - y / 3
I hope this helps. :)
