Answer:

P_D=61.1*10^{-4}

R_r=480

Step-by-step explanation:

From the question we are told that

Homicide rate in US R_U=62.4\ per\ one\ million

Homicide rate in Britain R_B=1.3\ per\ one\ million

Generally the equation for probability of homicide is mathematically given as

P=\frac{R}{10^6}

Generally the equation for probability of homicide in US is mathematically given as

P_U=\frac{62.4}{10^6}

P_U=62.4*10^{-4}

Generally the equation for probability of homicide in Britain is mathematically given as

P_B=\frac{1.3}{10^6}

P_B=1.3*10^{-5}

a)Generally the difference b/w the probabilities P_D is mathematically given as

P_D=P_U-P_B

P_D=62.4*10^{-4}-1.3*10^{-5}

P_D=61.1*10^{-4}

Therefore US annual homicide is P_D=61.1*10^{-4} greater than Britain's

b)Generally the Relative risk is R_r is mathematically given as

R_r=\frac{P_U}{P_B}

R_r=\frac{62.4*10^{-4}}{1.3*10^{-5}}

R_r=480

For a smoothing constant of 0.2

Time period – 1 2 3 4 5 6 7 8 9 10

Actual value – 46 55 39 42 63 54 55 61 52

Forecast – 58 55.6 55.48 52.18 50.15 52.72 52.97 53.38 54.90

Forecast error - -12 -.6 -16.48 – 10.12 12.85 1.28 2.03 7.62 -2.9
The mean square error is 84.12

The mean forecast for period 11 is 54.38
For a smoothing constant of 0.8

Time period – 1 2 3 4 5 6 7 8 9 10

Actual value – 46 55 39 42 63 54 55 61 52

Forecast – 58 48.40 53.68 41.94 41.99 58.80 54.96 54.99 59.80

Forecast error - -12 6.60 -14.68 0.06 21.01 -4.80 0.04 6.01 -7.80The mean square error is 107.17

The mean forecast for period 11 is 53.56


Based on the MSE, smoothing constant of .2 offers a better model since the mean forecast is much better compared to the 53.56 of the smoothing constant of 0.8.
