Given:
Investment (P) = $10000
Rate of interest (R) = 3.5%
Time (T) = 7 years
To find:
Amount in the account after 7 years
Solution:
Simple interest formula:
Simple interest = $2450
Amount = Investment + Interest
= 10000 + 2450
= 12450
Therefore $12,450 will be in the account after 7 years.
Answer:
Step-by-step explanation:
Data given and notation
represent the sampe size for A
represent the sample size for B
represent the sample deviation for A
represent the sample deviation for B
represent the significance level provided
F test is a statistical test that uses a F Statistic to compare two population variances, with the sample deviations s1 and s2. The F statistic is always positive number since the variance it's always higher than 0. The statistic is given by:
Solution to the problem
System of hypothesis
We want to test if we have the same variation, so the system of hypothesis are:
H0:
H1:
Calculate the statistic
Now we can calculate the statistic like this:
