Answer:
The 95% confidence interval of the proportion of all adults that have high blood pressure is 0.17059 <
< 0.314695
Step-by-step explanation:
The confidence interval for a proportion is given by the following formula;

Where:
x = 33
n = 136
= x/n = 33/136 = 0.243
z value for 95% confidence is 1.96
Plugging in the values, we have;

Which gives;
0.17059 <
< 0.314695
Hence the 95% confidence interval of the proportion of all adults that have high blood pressure = 0.17059 <
< 0.314695
From the above we have;
23.2 < x < 42.798
Since we are dealing with people, we round down as follows;
23 < x < 42.
it would equal the same mixed number. 5 2/3
Answer:
1 whole
Step-by-step explanation:
Multiply $530.40 by 3/4. You get the equation

If you simplify this, you get the solution of $397.80
$397.80
They are intersecting lines if they are not parallel so the other option is that they are intersecting.<span />
