Step-by-step explanation:
The given hypothesis are
Null hypothesis: H0:μ= 1.7
Alternative hypothesis: H1:μ≠ 1.7
The alternative hypothesis demonstrates that mean number of children are not 1.7 in 2000. This means that mean number of children can be greater than 1.7 or mean number of children can be less than 1.7. Thus, the given alternative hypothesis indicates the two tailed test.
The correct answer is A: a steel building.
Explanation:
A steel building will have the lowest premiums out of all the choices given above. After reading several insurance companies policies, a steel building has premiums 30% lower than any other homeowner policy. Steel is harder to destroy in a fire and the damage would be less than a wood home, mixed composition, or even an all brick home.
A wood home has the highest premiums out of all the choices given. When one catches on fire, they will burn fast and usually is a total loss unless the fire trucks get there in minutes.
A brick home can still be destroyed by fire on the inside even if the damage is minimal on the outside of the home.
A mixed composition home, will also be damaged by fire and could be a total loss unless fire trucks are there within minutes.
