The probability of selecting a 55 one-bedroom apartment is 1 and the value of z is 38.53.
Given,
Mean of rent of one bedroom apartment = $2075
The standard deviation of rent of the apartment = $300
n = 55
x' = $1985
We have to find x' to be at least $1985 which is P(x' > $1985).
The z-value is calculated from,
z = (x' - u)/√std. deviation/n
Putting the values, we get;
z = (1985 - 2075)/(√300/55)
or, z = -38.536
So, P(x' > $1985)
or, P(z > -38.5364)
This changes to:
P(z < 38.5364)
Hence the probability from the z distribution table is 1 and the value of z is 38.5364.

7,0 starts from 7 on the x-axis and stays there since it's 0. Then 0,7 starts from the origin on 0 and goes up 7.
