Answer:
Pew Research can get an accurate estimate by calling both cell phones and landlines. This is to also include some sample of the population that can be reached only through landlines.
Explanation:
When surveying a population for a particular factor or trait, a sample that is representative of the true population must be used. If Pew Research wants to get a correct estimate of the number of households using only cell phones, they need to also recognize the sample of the population that use landlines.
A small percentage of households still use landlines and these should be accounted for in any research or survey. Therefore, landlines should be used to reach households that use only landlines.
Answer: $61,328.15
Explanation:
The amount paid is per year so this is an annuity. It will begin 11 years from now so one should find the present value in that year:
Present Value of annuity = Annuity * ( 1 - ( 1 + rate) ^ - no. of periods) / rate
= 6,260 * ( 1 - ( 1 + 3%) ⁻¹⁷) / 3%
= $82,419.90
That is the present value if the annuity starts 11 years from now which means that it is the present value 10 years from now (ordinary annuities are paid end of period).
You need to discount to current period:
= 82,419.90 / ( 1 + 3%)¹⁰
= $61,328.15
Answer:
