Step-by-step explanation: ......
Answer: No, the percentage of the fleet out of compliance is not different from their initial thought.
Step-by-step explanation:
Since we have given that
n = 22
x = 5
So, 
he company initially believed that 20% of the fleet was out of compliance. Is this strong evidence the percentage of the fleet out of compliance is different from their initial thought.
so, p = 0.2
Hypothesis would be

So, the t test statistic value would be

Degree of freedom = df = n-1 = 22-1 =23
So, t{critical value} = 2.080
So, 2.080>0.353
so, we will accept the null hypothesis.
Hence, No, the percentage of the fleet out of compliance is not different from their initial thought.
