Answer for below mentioned points is in the attached image :
Use a decision tree to determine whether Moon should add capacity to its Santa Clara plant or if it should outsource to Molectron. What are some other factors that we have not discussed that would affect this decision?
Explanation:
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.
Answer:
John must invest $3719.4
Explanation:
It is given that John grandfather withdraws $120 per month for 3 year
So total month = 12 ×3 =36 months
Total amount withdrawn S = 36×120 = 4320
m = 12 times per year
Rate of interest i = 5 % = 0.05
We know that
P = $3719.41
So john must invest $3719.4
