Answer to Question #308569 in Statistics and Probability for Tempest

Question

n= 15 Percentile= 99.5th t(a,df)=

Answer 1

we define the following

degrees of freedom(df) = 15 Percentile= 99.5^th

1 - α =0.995

  α =0.005

P( t < t(α, df) ) = 0.995

From the t distribution table, t(α,df)  = 2.947 which is the required solution
