is les 30 pts pos Determine the t-value in each of the cases. Click the icon to view the table of areas under the t-distribution. (a) Find the t-value such that the area in the right tail is 0.20 with 6 degrees of freedom ·(Round to three decimal places as needed ) (b) Find the t-value such that the area in the right tail is 0.005 with 23 degrees of freedom (Round to three decimal places as needed) (c) Find the t-value such that the area left of the t-value is 0.05 with 10 degrees of freedom. (Hint. Use symmet pl (Round to three decimal places as needed.) (d) Find the critical t-value that corresponds to 96% confidence. Assume 1 1 degrees of freedom. (Round to three decimal places as needed.) idesExplanation / Answer
to calculate t value we can use t table as well as any other softwear, i have used excel,
a)df=6, t value = [=t.inv(0.80,6)]=0.906
2)df=23,
t value = [=t.inv(0.995,23)]=2.807
c)df= 10
t value =[=t.inv(0.05,10)]=-1.812
d)for 96% confidence,
probability in each tail = 0.02,
and critical t value=[t.inv(0.02,11)]=2.328
