Answer: The open interval would be (31.4,42.5).
Step-by-step explanation:
Since we have given that
mean = 36.9
Standard deviation = 16.5
n = 48
At 98% confidence interval, z = 2.33
So, Interval would be

Hence, the open interval would be (31.4,42.5).
The answer is 45 when you substitute all the variables in
