Answer:
H0:p1=p2; Ha:p1≠p2, which is a two-tailed test.
Step-by-step explanation:
We formulate our hypotheses as
H0:p1=p2; Ha:p1≠p2, which is a two-tailed test.
Supposing the probability or proportion of the first survey is equal to the probability or proportion of the second survey. This will be the null hypothesis and the alternative hypotheses would be that these two proportions or probabilities are unequal.
This is a two tailed test.
Answer:
Step-by-step explanation:
Rearrange the terms and take out a common factor of 4
4(8x^2 + 2x + 1)
I think this is as far down as you want to take it. It gives an imaginary root which you may not be familiar with.
Answer:
y = x^2+2x+1
Step-by-step explanation:
x^2+2x+1
= (x+1)^2
Answer:
21428.57
Step-by-step explanation:
Steps to solve "7500 is 35 percent of what number?" We have, 35% × x = 7500 or, 35 100 × x = 7500 Multiplying both sides by 100 and dividing both sides by 35, we have x = 7500 × 100 35 x = 21428.57 If you are using a calculator, simply enter 7500×100÷35, which will give you the answer.
