Answer:
$70,201.38
Step-by-step explanation:
To determine the principal amount, we can use the formula:
A = $200,000
r = 7% or 0.07
t = 15 years
n = 12
Now let's substitute our values.
So the principal needed to get 200,000 in 15 years is $70,201.38.
Answer:
C) There is not sufficient evidence to support the claim that the mean attendance is greater than 523.
Step-by-step explanation:
Let μ be the the average attendance at games of the football team
The claim: the average attendance at games is over 523
Null and alternative hypotheses are:
The conclusion is failure to reject the null hypothesis.
This means that <em>test statistic</em> is lower than <em>critical value</em>. Therefore it is not significant, there is no significant evidence to accept the <em>alternative</em> hypothesis.
That is no significant evidence that the average attendance at games of the football team is greater than 523.
