Answer:

<u>Statistical Inference</u>

Explanation:

Sampling refers to a form of statistical analysis wherein some items from the whole population are selected for analysis, the results of which would represent the collective result had all the observations been selected and subjected to analysis.

Sampling risk is inversely related to the size of the sample.  Higher the sample size, more accurate would be the results and thus lesser the sampling risk.

In the given case, the sample size is 800 students. The results derived from the analysis of the said sample have been construed to be true for all the students of the university which includes those students which did not form part of the sample size.

This is referred to as statistical inference as sampling being a statistical tool.

year 1 = $425,000

year 2 = $425,000 x 1.08 = $459,000

year 5 = $578,208

year 6 = $624,464

year 7 = $674,422

year 8 = $728,375

year 9 = $786,645

year 10 = $849,577

year 11 = ($849,577  x 1.08) - $480,000 = $917,543 - $480,000 = $437,543

guapka [62]

Answer:

Explanation:

Using future annuity formula

Fv = Pmt ( (1+r)ⁿ -1 )/ r

\frac{FVr}{Pmt}  + 1 = (1+r)ⁿ

In ( \frac{FVr}{Pmt} + 1) = n In ( 1+r)

n =  In ( \frac{FVr}{Pmt} + 1)  / In ( 1 + r)

FV, future value = $10,000, Pmt, periodic payment per year = $1,100, r rate = 11.82% = 0.1182 and n =  number of years

n = 0.7297 / 0.11172 = 6.53 years approx 7 years

the last year payment will actually be less than $1,100
