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.

Answer:
a. automatic stabilizers.
b. automatic stabilizers.
Discretionary spending
Discretionary spending
Explanation:
Automatic stabilizers are stabilizers that adjust the economy automatically without the intervention of external agents . examples include progressive tax and transfer payments
In an expansion, progressive tax increases the tax paid and this reduces disposable income
In a contraction, tax paid is reduced and this increases disposable income
Discretionary fiscal policies are deliberate steps taken by the government to stimulate the economy in order to cause the economy to move to full employment and price stability more quickly than it might otherwise.
Discretionary fiscal policies can either be expansionary or contractionary
Expansionary fiscal policy is when the government increases the money supply in the economy either by increasing spending or cutting taxes.
Contractionary fiscal policies is when the government reduces the money supply in the economy either by reducing spending or increasing taxes
