Incomplete question
First aspect of the question is typed below.
The shape of the distribution of the time required to get an oil change at a 20-minute oil-change facility
is unknown. However, records indicate that the mean time is 2l.2-minutes, and the standard deviation 3.5 minutes.
Explanation:
Employees bonus $50
35 oil changes between 10:00 am to 12:00pm
n = 35
10% changes
So, the z - score can be calculated using
z-score = InvNorm(0.10)
z-score = -1.28
So, given that,
Standard deviation is 3.5minutes
σ = 3.5 minutes
Mean time is 21.2 minutes
μx = 21.2 minutes
Then,
σx = σ / √n
σx = 3.5 / √35
σx = 0.5916 minutes
Then, Z score can be written as
Z = (x - μx) / σx
-1.28 = (x - 21.2) / 0.5916
Cross multiply
-1.28 × 0.5916 = x - 21.2
-0.7573 = x - 21.2
x = 21.2 - 0.7573
x = 20.443 minutes
There is a 10% chance of being at or below a mean oil-change time of 20.44 minutes

Answer:
sticky in both an upward and downward direction
Explanation:
nominal wages are wages been earned per hour or as agreed between the worker and the employer. it is seen as means of compensating the worker. it is called nominal wage because the effects of deflation ( downward direction of prices in the market ) and inflation ( upward direction of prices in the market) does not affect the Nominal wages of an employee hence it is sticky in both an upward and downward direction of price movement in the market.
unlike the real wages where the factors of inflation and deflation has an effect on it by either decreasing or increasing the purchasing power of the real wage.
