Answer:
a) 15 to 35 approximately 95%
(b) 10 to 40 approximately almost all
(c) 20 to 30 approximately 68%
Explanation:
The data have a bell-shaped distribution which means the data is equally distributed on both sides of the mean.
We have the mean at 25 and a standard deviation of 5 which means that the interval is for each of the values of 5 .
The mean would be u and
The first value would be u ±σ = 25 ± 5= 20 and 30 (68 % )
The second value will be u ± 2σ= 25± 10 = 15 and 35 (95%)
The third value will be u ± 3σ= 25 ± 15 = 10 and 40 (99.7 % almost all)
In the figure below the light blue region gives u ±σ on both sides of the mean
, dark blue gives u ± 2σ values on both sides of the mean and grey gives
u ± 3 σ values on both sides of the mean.
It is obvious that 68 % of the data is contained in the u ±σ light blue region, 95 % of the data in the u ± 2σ dark blue including light blue and 99.7 % in the u ± 3σ all colored regions.

Firstly, the former manager who retired increased sales by 15 percent every year for the past five years. Secondly, based on the performance of recent Wharton graduates, who were managers at three additional stores owned by Kristin's company and were able to perform better than this former manager who just retired by increasing sales by 18 for the past three years in their respective stores. Kristin can therefore conclude to higher Roger Benson to repeat the same stellar performance.
