Step-by-step explanation:
We know that the mean is 35 and the median is 31.2 hours.
- Step 2: If we clear n of the percentil formule of the 6th percentile:
(n)()= 24 families → n=400 families.
- Step 3: true. The half of the population is 200. Therefore the 50% of the sample(the 50th percentile) is under or equal 31.2
- Step 4: By definition the median is the 50th percentil. So the 50 percentil → 31.2.
- Step 1: If we considerate that the 50th percentil is 31.2, a bigger percentil had to be bigger too.
- Step 5: False. At the beggining we have that the 6% of the population were below or equal to 20 hours, therefore the 25% of the data have to be greater or equal to 20.
Hi there
The formula of the future value of annuity ordinary is
Fv=pmt [(1+r)^(n)-1)÷r]
Solve the formula for n
Fv/pmt=(1+r)^(n)-1)÷r
cross multiplication
(Fv/pmt)×r=(1+r)^(n)-1
(Fv/pmt)×r+1=(1+r)^(n)
take the log for both sides
Log ((Fv/pmt)×r+1)=n×log (1+r)
Divide each side by log (1+r)
N=[Log ((Fv/pmt)×r+1)]÷log (1+r)
Now solve to find n
N=log((11,000÷200)×0.02+1)
÷log(1+0.02)
=37.47 years round your answer to get 37 years
