Answer:
GDP contribution is $6.
Explanation: GDP refers to the market value of final goods and services produced withing the national territory of a country.
Using the value added method, we can calculate GDP by summing up the value added at each level of production.
Or
Using the expenditure approach, GDP is the market value of the final good sold to the customer.
GDP = Cost of bread to the engineer = $6
Answer:
Since the calculated value of F= 5.733 falls in the critical region we reject the null hypothesis and conclude all three means are not equal.
Explanation:
The given data is
Banking Retail Insurance
12 8 10
10 8 8
10 6 6
12 8 8
<u>10 10 10</u>
The results of excel are:
<u><em>Anova: Single Factor </em></u>
SUMMARY
Groups Count Sum Average Variance
Column 1 5 54 10.8 1.2
Column 2 5 40 8 2
Column 3 5 42 8.4 2.8
1) Let the null and alternate hypotheses be
H0: u1=u2=u3 i.e all the three means are equal and
Ha: Not all three means are equal
2) The significance level is set at ∝ =0.05
3)The test statistic to use is
F= sb²/ sw²
which has F distribution with v1= k-1 →3-1=2 and v2= n-k →15-3=12 degrees of freedom
After calculations the following table is obtained.
<u><em>ANOVA </em></u>

<u>Within Groups 24 12 2 </u>
<u>Total 46.93 14 </u>
4) The critical region is F ≥ F(0.05, 2,12) = 3.885
5) Since the calculated value of F= 5.733 falls in the critical region we reject the null hypothesis and conclude all three means are not equal.
