Answer:

Let level of significance is $\alpha$ =0.05

Since p-value is greater than alpha so students' mean score does not significantly differ from the national average.

Correct option is:

His students' mean score does not significantly differ from the national average, because his p-value is greater than alpha.

Let level of significance is $\alpha$ =0.10

A: $\frac{5}{3} = \frac{N}{12}$
Multiply both sides by 12
Answer: $N = 20$

B: $\frac{7}{2} = \frac{42}{N}$
Multiply both sides by 2, $7 = \frac{84}{N}$
Multiply both sides by N, $7N = 84$
Divide both sides by 7,
Answer: $N=12$

C: $\frac{N}{2}= \frac{50}{N}$
Multiply both sides by 2, $N = \frac{100}{N}$
Multiply both sides by N, $N^{2} = 100$
Simplify,
Answer: $N = 10 , -10$

Hope I helped you!
