Answer:
a) 0.4770
b) 3.9945
c) z-statistics seem a large value
Step-by-step explanation:
<u>a. Find the standard deviation of the sample proportion based on the null hypothesis</u>
Based on the null hypothesis:
: 0.35
and the standard deviation σ =
=
≈0.4770
<u>b. Find the z statistic</u>
z-statistic is calculated as follows:
z=
where
- X is the proportion of employees in the survey who take advantage of the Credit Union (
)
is the proportion in null hypothesis (0.35)- s is the standard deviation (0.4770)
- N is the sample size (300)
putting the numbers in the formula:
z=
= 3.9945
<u>c. Does the z statistic seem like a particularly large or small value?</u>
z-statistics seem a large value, which will cause us to reject the null hypothesis.
The question is not defined very well so if u would repeat it
Answer:
1.about 180 degrees
2.45 degrees
3.1.5
4.4/5
Step-by-step explanation:
The solution to this equation is n= -49.6.
n/4=-12.4
n/4*4=-12.4 * 4
n= -49.6
The degree is nothing more than the highest exponent value. The degree of this expression would be 5
