Answer:
39 m.
Step-by-step explanation:
The area of a triangle is calculated by the expression given as:
Area = bh/2
where b is the base and h is the height.
We calculate as follows:
270 = b (15) / 2
b = 36
hypotenuse = sqrt ( 15^2 + 36^2 ) = 39

Step-by-step explanation:
Answer:
Yes, the given analysis involves a statistical test. Population parameter of interest = '% of community people living in mobile homes' (MH)
- H0 : MH = 0.09
- H1 : MH > 0.09
Step-by-step explanation:
Hypothesis testing is a statistical test, of testing an assumption (statement) about population parameter.
Null Hypothesis [H0] is a neutral statement of 'no difference' about a population parameter; stating variable is no different than its mean.
Alternate hypothesis [H1] is the 'specific difference' stating hypothesis about a population parameter; contrary to the null hypothesis.
To determine if there is evidence for the claim that the percentage of people in the community living in a mobile home is greater than 9% :
This analysis can be done by using statistical test : one sided 't' test. The population parameter of interest would be '% of community people living in mobile homes' (MH)
- H0 : MH = 9% → MH = 0.09
- H1 : MH > 9% → MH > 0.09
