A simple random sample of size 10 has a mean of 65.0 and a sample standard deviation of 8.0. A student would like to test the null hypothesis, ?0:?=70.0H0:μ=70.0, against the alternative, ?1:?<70.0H1:μ<70.0. Construct a confidence interval corresponding to this test at significance level ?=10%α=10%. Give your answer precise to two decimal places. lower limit =     upper limit =
