For this case we have the following equation:
Applying distributive property to the terms within the parentheses on the left side of the equation we have:
Subtracting "x" on both sides of the equation we have:
Subtracting 4 on both sides of the equation we have:

Answer:
We failed to accept null hypothesis
Step-by-step explanation:
x= 5.74
Standard deviation =
n = 65
We will use z test
Formula :
Substitute the values :
Refer the z table for p value
p value = 0.0314
α = 0.10
p value < α
So, we failed to accept null hypothesis
