Given α = 0.05, with 10 degrees of freedom,
calculate the right-tailed and left-tailed critical value for t
Calculate right-tailed value:
Since α = 0.05, the area under the curve is 1 - α → 1 - 0.05 = 0.95
Our critical t value is 0.0643
Excel or Google Sheets formula:
Excel or Google Sheets formula:=TINV(0.95,10)Calculate left-tailed value:
Our critical t-value = 2.2281
Excel or Google Sheets formula:
Excel or Google Sheets formula:=TINV(0.05,10)Final Answers
(left tail, right tail) = (0.0643, 2.2281)
What is the Answer?
(left tail, right tail) = (0.0643, 2.2281)
