Answer #1

the critical value of t for a 90% confidence interval with df =6 is: 1.943 ()

[ explanation:-

confidence level (c) =90% = 0.90

level of significance () = (1-c) = (1-0.90) = 0.10

using t distribution table for df = 6, alpha = 0.10 , for both tailed test or in any blank cell of excel type =T.INV.2T(0.1,6) ]
