the letter "r" is used in place of your "x"
scroll down to find 10 in the far left column for n
In the next column under r find 8.
Go to the column for .30 (the 7th column right of the
vertical line.)
Read the number .001
b. n = 8, x = 7, p = 0.95
scroll down to find 8 in the far left column for n
In the next column under r find 7.
Go to the column for .95 (the last column on the right.)
Read the number .279
