Answer:
H0: p(1980) = p(2010) ; H1 : P(1980) > P(2010)
0.02
Step-by-step explanation:
Given that:
Sample size in both 1980 and 2010 = 1000 samples :
Proportion in favor :
P(1980) = 0.66
P(2010) = 0.64
To test the hypothesis :
Null hypothesis :
Proportion in favor are the same in both years
Null hypothesis = H0 = p(1980) = p(2010)
Alternative hypothesis :
Proportion in favor in 1980 is greater than that in 2010
Alternative hypothesis = H1 : P(1980) > P(2010)
The sample statistic :
P(1980) - p(2010)
0.66 - 0.64
= 0.02
Answer:
Step-by-step explanation:
volume=l×w×h=14×5×8=560 inches³
Answer:
- 3x + 1 = 10
- 12 -x = 3x
- 5(x -1) = 10
Step-by-step explanation:
A "two step" equation is one that requires two steps to solve. The solution process generally involves adding something and multiplying by something, usually the inverse of the coefficient of the variable. The order of the steps may be reversed in some cases (such as the last one shown above).
So, to make up an equation, we can pick a multiplier and an added constant and choose any remaining term to make the solution be what we want.
