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.
Briar Co. disposed of a $6,000 piece of equipment on December 31 with $4,500 in accrued depreciation as of that date. Then $1,500 will be debited from the Loss on Equipment Disposal account.
<h3>What is loss on Equipment Disposal account?</h3>Gain/Loss on Asset Disposal is a common account name of the Equipment Disposal account.
The net difference between the initial asset cost and any cumulative depreciation (if any) is debited to the disposal account, while the balances in the fixed asset account and the accumulated depreciation are reversed.
On December 31, the debited amount is calculated as:
Therefore, $1,500 will be the amount of loss on disposal of the Equipment.
