Answer:
20%, 40%, 60%, 80%
Step-by-step explanation:
There is not enough evidence to support the administrator’s claim and the true mean is not significantly greater than 280.
<h3>What is a statistical hypothesis?</h3>
A hypothesis to test the given parameters requires that we determine if the mean score of the eighth graders is more than 283, thus:
The null hypothesis:
The alternative hypothesis:
From the population deviation, the Z test for the true mean can be computed as:
Z = 0.756
Note that, since we are carrying out a right-tailed test, the p-value for the test statistics is expressed as follows:
P(z > 0.756)
P = 0.225
Since the P-value is greater than the significance level at α = 0.14, we can conclude that there is not enough evidence to support the administrator’s claim and the true mean is not significantly greater than 280.

The formula for compound interest growth is
A=P×(1+r/100)^t
Where
A= end amount
P= principle amount
r= rate
t= time in years
Plug your numbers into the formula:
A=936×(1+(5.5/100))^1
A=$987.48
So the end amount is $987.48
