Answer:
H₀: µ ≤ $8,500; H₁: µ > $8,500
z= +1.645
Step-by-step explanation:
From the given problem As average cost of tuition and room and board at a small private liberal is less than the financial administrator As hypothesis is true.
As standard deviation is $ 1,200
α = 0.05
H₀: µ ≤ $8,500
if the null hypothesis is true then value for critical z is +1.645.
Simply ,
5
Since the product of the square root of 5 ,
Gives 5
Therefore x is also equal to 5
Place a point on the 2 on the y-axis. Place another point on 1.3 on the x-axis. Then draw a straight line through the points from top left to bottom right.
