Answer 1

My dear student as per HomeworkLib policy i am allowed to solve one question at a time so I am solving the first question in the pic. Thank you

2. Test is left tailed .

So p( T<t) = 0.1

degree of freedom is 11

Using t table at df= 11

t= -1.36

So critical value here is -1.36 option (d)
