Answer:
Test: 
< 20 with normal distⁿ
Hypothesis test:
H0: 
20 (Null Hypothesis, H₀ : = 20 is also correct)
H1: < 20 (Alternative Hypothesis, also called H₁)
This is lower tailed test.
Since sample is large, sample standard deviation can be taken as an approximation of population standard deviation.
x = 19.3
= 11.1
n = 444
significance level, 
= 0.05 (If no value is given, we take level of 0.05)
Test statistic 
= - 1.33
