Answer:
Reject H0 if x > cv
Step-by-step explanation:
The hypothesis :
H0 : μ ≤ 425
H1 : μ > 425
Standard deviation, s = √2500 = 50
Sample size, n = 100
xbar = 433.5
The test statistic, Z :
(xbar - μ) / s/√n
(433.5 - 425) / 50/10
Z = 8.5 / 5 = 1.7
The decision region ;
|Z| > Z0.01 ; Reject H0
From Z table ;critical value, Z0.01 = 2.33
1.7 < 2.33 ; We fail to reject then Null and conclude that thee is no significant evidence support the claim that population mean income has increased.
