Solving:
We know,
a^0 = 1
so,
So, the value of
The answer is the first page, first graph
Answer:
Use the normal distribution if the population standard deviation is known.
Use the student's t distribution when the population standard deviation is unknown.
Explanation:
A mound-shaped distribution refers to the normal distribution.
A good sample size for testing against the normal distribution should be
n >= 30.
The condition for the sample size is satisfied.
However, we are not given the population standard deviation, therefore it is assumed to be unknown.
Therefore the student's t distribution should be used.
You can't at standard temperature and pressure. Minimum temperature needed is about 130 F and it would take about 20 minutes at that.
A) The total installment price is ($28/mo)*(24 mo) = $672.00
b) The carrying charges are $672.00 -500.00 = $172.00
c) The number of months of saving required is 500/28 ≈ 18.
