Question

Consider the value of t such that the area under the curve between −|t| and |t| equals 0.9. Assuming the degrees of freedom equals 10, select the t value from the t table.

Answer 1

Answer:

the value of t such that the area under the curve between - t and t equals 0.9 then,

level of significance = 0.1 = 10%

sample size n=11

degree of freedom = n-1 = 11 - 1 = 10

Critical Value

The Value of t α at 0.1 LOS with n-1 =10  is +1.812 and -1.812
