Use Pascal’s triangle to find the possible value(s) of nn if nC3=(n3)=20.

Expert Solution

I guess u want to find n such that nC3=20 using pascal triangle. and this is the only soln. Bcoz if u write the next few rows of pascal triangle and observe each of the 4 th number of each row after 6th tgey are all greater than 20 and the value keep on increasing also.

For a hypothesis t-test, what is the easiest way to find the p-value (if possible) without using technology? I'm using a two-tailed test and a right-tailed test with t-values = 2.95, n=18 for the two-tailed and t-value = 3.0, n=40 for the right-tailed. Will I be able to calculate the p-values by using table A-3?
