Answer: 1.467
Step-by-step explanation:
Formula of Margin of Error for (n<30):-
Given : Sample size : n= 22
Level of confidence = 0.90
Significance level :
By using the t-distribution table ,
Critical value :
Standard deviation:
Then, we have
Hence, the margin of error for the confidence interval for the population mean with a 90% confidence level =1.467
