Determine the value of A such that PF A 99 where F has u

Determine the value of A such that P(F > A) = .99, where F has u = 10 and v = 15 degrees of freedom.

-Can you show me how to do this in a TI-83??

Solution

P(F > A) = .99,

We have to find critical value using TI-83 calculator.

u=10 and v=15 degrees of freedom.

But we can\'t find critical value using TI-83 calculator.

We can find the critical value for F-distribution using EXCEL and statistical table.

EXCEL syntax:

=FINV(probability,deg_freedom1,deg_freedom2)

where probability = 0.99

deg_freedom1 = 10

deg_freedom2 = 15

A = 0.219388
