Answer:

$y^6$ , $12n^6$ , $20x^9$

Step-by-step explanation:

When you multiply like variables with each other, you add their powers together.

So...

1. $(y^2)(y)(y^3)\\y^{2+1+3} \\y^6$

2. $(3n^2)(4n^4)\\12n^{2+4}\\12n^6$

3. $(5x^4)(4x^5)\\20x^{4+5}\\20x^9$

Since the test says to test whether the proportion of skiers is not 0.50, then here we will be studying just only the promotion of skiers without the comparison with snowboarders.

We have been given an hypothesized promotion and the test says to test against this proportion, so the appropriate test to use here is the one sample test of proportions
