Answer:
New balance = $316.8
Step-by-step explanation:
Given : Maya's unpaid balance is $205.16. Her APR is 14.4% and she has $82.10 in new transactions.
To find : What is her new balance?
Solution : First we find out the finance charge
Unpaid balance = $205.16
Finance rate = 14.4%
Finance charge = Unpaid balance × finance rate
Finance charge = $29.54
New purchase = $82.10
New balance = Unpaid balance + finance charge + new purchase
New balance = $205.16 + $29.54 + $82.10
New balance = $316.8
Answer:
We know that In 1990, the mean duration of long-distance telephone calls originating in one town was 7.2 minutes. And we want to test if the mean duration of long-distance phone calls has changed from the 1990 mean of 7.2 minutes (alternative hypothesis) and the complement rule would represent the null hypothesis.
The correct system of hypothesis are:
Null hypothesis:
Alternative hypothesis:
So then the best option for this case would be:
H0: μ = 7.2 minutes Ha: μ ≠ 7.2 minutes

And in order to test the hypothesis we can use a one sample t test or z test depending if we know the population deviation or not
