Answer:
m<CDE=66 degrees.
Step-by-step explanation:
(1) Extend the segment DC so it intersects with line BA. Call the intersection F.
(2) Consider triangle BCF. In here, we are given m<ABC=24 deg. Since m<BCD = 90 deg, we known that m<BCF = 90 deg. Knowing two angles in the triangle BCF lets us determine the rhird angle m<BFC = 180-90-24 = 66 deg.
(3) Because of the fact that AB || DE and the fact that line DF intersects AB and DE, the angles <BFC and <CDE are congruent. Therefore m<CDE=66 deg.
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
0.9^50=0.0051537752That's your answer.<span>
