Step-by-step explanation:

The null hypothesis (H0) tries to show that no significant variation exists between variables or that a single variable is no different than its mean.

While an alternative Hypothesis (Ha) attempt to prove that a new theory is true rather than the old one. That a variable is significantly different from the mean.

For the case above, the mean door height is 80 inches

H0 : u = 80 inches

A) 672750
B) 68250
C) 2960100

Explanation
A) We have 26 letters from which to choose 4, and 10 digits from which to choose 2:
$_{26}C_4\times_{10}C_2=\frac{26!}{4!22!}\times\frac{10!}{2!8!}=14950\times45=672750$

B) We have 26 letters from which to choose 2, and 10 digits from which to choose 4:
$_{26}C_2\times_{10}C_4=\frac{26!}{2!24!}\times\frac{10!}{4!6!}=325\times210=68250$

C) We have 26 letters from which to choose 5, and 10 digits from which to choose 2:
$_{26}C_5\times_{10}C_2=\frac{26!}{5!21!}\times\frac{10!}{2!8!}=65780\times45=2960100$
