Answer 1

Answer #1

The statistical software output for this problem is:

One sample Z summary hypothesis test:
? : Mean of population
H₀ : ? = 50
H_A : ? ? 50
Standard deviation = 3

Hypothesis test results:

Mean	n	Sample Mean	Std. Err.	Z-Stat	P-value
?	9	53	1	3	0.0027

Hence,

p - Value = 0.0027

Option B is correct.
