Statistical Tables and Chart Part 1 Correct. Confidence level=95%, degrees of freedom=14 1.761 e Textbook and Media Attempts: 1 of 3 used Part 2 Confidence level=99%, degrees of freedom=19

Answer 1

$\\ Part:-I\\\\ Significance(\alpha)=0.05\\\\ Degree~of~freedom=14\\\\ critical~Value(t_{\alpha})=1.761\\\\ (Use~excel~function:=TINV(0.05*2,14))\\\\ Ans:1.761$

$\\ Part:-II\\\\ Significance(\alpha)=0.01\\\\ Degree~of~freedom=19\\\\ critical~Value(t_{\alpha})=2.539\\\\ (Use~excel~function:=TINV(0.01*2,19))\\\\ Ans:2.539$
