Answer:
Confidence interval for the mean amount = 54+1.645*21/sqrt(16) =(62.64 , 45.36)
Explanation:
confidence interval = mean + z*, where z* is the upper (1-C)/2 critical value for the standard normal distribution.
z score for 90% confidence interval = 1.645
confidence interval for the mean amount = 54+1.645*21/sqrt(16) =(62.64 , 45.36)
