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.

Answer:
So then the difference between the two proportions is 0.045 and if we convert this into % we got
Step-by-step explanation:
For this case we can define the following notation:
represent the unemployment rate for high school graduates with no college degree
represent the unemployment rate for college graduates with a bachelor's degree
And for this case we need to find the difference in proportions of those unemployed between these two groups, we want to find:
From the info given we have 
And the difference:
So then the difference between the two proportions is 0.045 and if we convert this into % we got
I think it is 1, 4, and 5
There are 12 squares in each 4 x 3 grid.
25% of 12 = 3
This means that there should be 3 shaded squares in the grid.
Your answer is B. because it has 3 shaded squares.
