First you had to add by seven from both sides of equation form.
Then simplify by equation.
Next, you multiply by two from both sides of equation form.
And finally, simplify by equation.
Final answer:
Hope this helps!

ANSWER
EXPLANATION
Use the Pythagoras Theorem to obtain,
This implies that,
Take the positive square root of both sides to get,
Answer:
The standard deviation used in the test statistic is 0.04.
Step-by-step explanation:
A single proportion <em>z</em>-test can be used to determine whether the proportion of people in Norway with a blood type of A positive is different from that in the United States.
The proportion of people in Norway with a blood type of A positive is 36% or 0.36.
The hypothesis can be defined as:
<em>H₀</em>: The proportion of people in Norway with a blood type of A positive is 36%, i.e. <em>p</em> = 0.36.
<em>Hₐ</em>: The proportion of people in Norway with a blood type of A positive is different from 36%, i.e. <em>p</em> ≠ 0.36.
The test statistic is:
The information provided is:
<em>p</em> = 0.36
<em>n</em> = 150
Compute the standard deviation used in the test statistic as follows:
Thus, the standard deviation used in the test statistic is 0.04.
