Caiden's balance after 5 years would be $831
<u>Explanation:</u>
Given:
Principal, p = $475
Rate of interest = 3.8%
time, t = 15 years
Balance after 15 years = ?
We know:
where,
n = number of compounding periods
r = rate of interest
t = number of years
Substituting the value;
Therefore, Caiden's balance after 5 years would be $831
Answer:
We see that the p value i higher than the significance level so then we FAIL to reject the null hypothesis and we can conclude that the true mean is not significantly higher than 13.2 *the value of 2008 ).
Step-by-step explanation:
Information given
represent the sample mean
represent the sample standard deviation
sample size
represent the value that we want to test
represent the significance level
t would represent the statistic (variable of interest)
represent the p value for the test
Hypothesis to test
We want to conduct a hypothesis in order to check if the true mean has increased from 2008 , and the system of hypothesi are:
Null hypothesis:
Alternative hypothesis:
The statistic for this case is:
(1)
Calculating the statistic
Replacing the info given we got:
P-value
The degrees of freedom are:
Since is a right tailed test the p value is:
Decision
We see that the p value i higher than the significance level so then we FAIL to reject the null hypothesis and we can conclude that the true mean is not significantly higher than 13.2 *the value of 2008 ).
