Answer:
Because z is higher than any given value in the chart we come to the conclusion To reject null hypothesis
Step-by-step explanation:
Sample proportion = p= 531/648 = 0.8194
This is the proportion of men that were hit by lightening
Null hypothesis: H0: p = 0.5
Alternate hypothesis: H1: p ≠ 0.5
Test statistics z = 0.8194-0.5/(√0.5x0.5/648)
= 0.8194-0.5/√0.0003858
= 0.3194/0.019642
= 16.26
Since the z > 1.96 (at 5% significance) we reject the null hypothesis.
Therefore in conclusion we say z is higher than given values in the chart so we reject null hypothesis.

We know a or b != 0
but a-b==0 so both are the same unknown number
b/a must = 1
so
a/b is equivalent to b/a as a/b=1 as well.
So the last answer choice.
The distance of it away from zero cannot be a negative distance, distance is always positive therefor the absolute value will always be positive.
Short answer: no, absolute value is always positive
I hope this helps :)
Hello!
You put -1 in for x
F(-1) = (-1)^5 + (-1 + 3)^2
F(-1) = -1 + (2)^2
F(-1) = -1 + 4
F(-1) = 3
The answer is 3
Hope this helps!
