Answer: z(e) = 2.07
Step-by-step explanation:
1.-The problem is about a test of proportions. As research company claims than no more 55 % of Americans regularly watch Fox News
The null hypothesis is H₀ P₀ ≤ 0.55 from 55%
And the alternative hypothesis is Hₐ Pₐ > .55
Is one tail test
2.-We have to specify significance level we assume our test will be for a significance level α = 5% or α = 0,05
3.-Calculation of z (c) = ?? and z (e) = '??
For z (c) we find in z table the value of z(c) = 1.64
For z (e) = ( P -P₀)/√p₀q₀/n z(e) = 0.05 / √(0.55*0,45)/425 z(e) = 0,05/ 0.02413 z(e) = 2.07
z(e) > z(c) threfore z(e) is in the rejection zone . We reject null hyothesis

To me it sounds like 4 divided by n +5
plug 9 in for t
3(9)-5=27-5=22
hope it helps comment if you have any questions have an amazing day
To answer this question, we need to write all sets of numbers that the given number belongs to.
For the first one, which is -4/5, it belongs to rational numbers and also to real numbers. We know this because it can be wrote in the form a/b (rational number) and if it is a rational number it has to be a real number.
It is not an integer or a natural number.
