Answer: 95% certain that true proportion of population "p" is contained in (0.604, 0.781)
Step-by-step explanation:
We know that a 95% confidence interval is a range of values that you can be 95% sure that true mean of the population or true proportion of population lies in it .
Given : The 95% confidence interval for p was calculated to be (0.604, 0.781).
It means that we are 95% certain that true proportion of population "p" is contained in (0.604, 0.781).
Hence, the correct interpretation for this interval :- 95% certain that true proportion of population "p" is contained in (0.604, 0.781).
Answer:
(x+1)(x-1)(x+3)(x-3)
Step-by-step explanation:
x4-10x^2+9
Group expression so that the coefficients of the x^2 terms add up to +9.
= x^4 -9x^2 - x^2+9
match coefficients in both groups
= x^4 -9x^2 - (x^2-9)
factor each group
= x^2 (x^2-9) - 1(x^2-9)
now factor out the common factor (x^2-9)
= (x^2-1)(x^2-9)
Finally, factor each quadratic factor
= (x+1)(x-1)(x+3)(x-3)
