Using the z-distribution, it is found that the p-value is of 1.
At the null hypothesis, it is tested <u>that the majority is not against the death penalty</u>, that is:
At the alternative hypothesis, it is <u>tested that the majority is against the death penalty</u>, that is:
The test statistic is given by:
In which:
is the sample proportion.
- p is the proportion tested at the null hypothesis.
- n is the sample size.
In this problem, the parameters are: .
Then, the value of the <em>test statistic</em> is:
Using a z-distribution calculator, for a <u>right-tailed test</u>, as we are testing if the proportion is greater than a value, the p-value is of 1.

Answer:
f(x) = (4x - 1)(2x + 1)
The zeros of the function are and
.
Step-by-step explanation:
The given quadratic expression is 8x² - 2x - 3.
Now, the factorization of this quadratic expression gives:
f(x) = 8x² - 2x - 3
⇒ f(x) = 8x² - 6x + 4x - 3
⇒ f(x) = 2x(4x - 3) + 1(4x - 3)
⇒ f(x) = (4x - 1)(2x + 1)
Hence, the zeros of the function are and
