Step-by-step explanation:
Given that in a random sample of 42 people, the mean body mass index (BMI) was 28.3 and the standard deviation was 6.09.
Since only sample std deviation is known we can use only t distribution
Std error = 
t critical for 99% two tailed 
Margin of error
Confidence interval lower bound = 
Upper bound =
