Using the concepts of parameter and statistic, it is found that the correct option is:
- 2% is a statistic and 5% is a statistic.
<h3>Parameter and Statistic:</h3>
- If the information is taken from a sample, it is called a statistic.
- If the information is taken from a population, it is called a parameter.
In this problem, both percentages are taken from samples, hence both the 2% and the 5% represents statistics, and the first option is correct.

Answer:
z= 2.38
P = 0.008656
Step-by-step explanation:
Here n= 500 and p~= 464/500= 0.928 and q`= 1- 0.928 = 0.072
We formulate our null and alternate hypothesis as
H0 = 0.9 ; H0 > 0.9
The degree of confidence = 90%
z₀.₀₅ = 1.645 for α= 0.05
We use the test statistic
z= x- np/√npq
z= 466-500 *0.9/ √500 * 0.9(1-0.9)
z= 466- 450/ √45
z= 16/6.7082
z= 2.38
As the calculated value of z= 2.38 is greater than α =1.645 so we reject H0.
If H0 is true the P value is calculated as
P = 1- Ф( 2.38)
P = 1-0.991344=0.008656
The answer is 12 if I’m wrong sorry
Answer:
13/2
Step-by-step explanation:
-8 minus 18 gives you 26
then, -20 minus -16, which is equal to +16 gives you -4
after that you would simplify all the way to 13/2
