Question 1155869: Assume that a sample is used to estimate a population mean. Find the 90% confidence interval for a sample of size 34 with a mean of 42.8 and a standard deviation of 13.6. Enter your answer as a tri-linear inequality accurate to one decimal place (because the sample statistics are reported accurate to one decimal place.)

t 0.95 df=33=1.69
half-interval is t*s/sqrt(n)
=1.69*13.6/sqrt(34)
=3.94
this is the distance on either side of the mean, 42.8
(38.9
