Barron's has collected data on the top 1,000 financial advisers. Company A and Company B have many of their advisers on this lis

t. A sample of 16 of the Company A advisers and 10 of the Company B advisers showed that the advisers managed many very large accounts with a large variance in the total amount of funds managed. The standard deviation of the amount managed by the Company A advisers was s1 = $583 million. The standard deviation of the amount managed by the Company B advisers was s2 = $489 million. Conduct a hypothesis test at α = 0.10 to determine if there is a significant difference in the population variances for the amounts managed by the two companies. What is your conclusion about the variability in the amount of funds managed by advisers from the two firms? State the null and alternative hypotheses.

Answer:

We'll start by putting into consideration, the large sample variance at the numerator.

Barron's Variance will be represented using 1 as the subscript.

i.e.

1 = $583 million

2 = $489 million

So,

0: 1²= 2²

: 1² ≠ 2²

=1² / 2²=

= $583 million² / $489 million²

= 583²/489²

= 1.42

Degrees of freedom 15 and 9

Using F table, area in tail is greater than 0.10.

Two-tail p-value is greater than .20

Exact p-value corresponding to F= 1.42 is .5874 (See F table)

p-value > .10

So,we do not reject 0.

We cannot conclude there is a statistically significant difference between the variances for the two companies.

CASE STUDY: MCNULTY’S MUSCULAR MATERIALS (MMM)
denis-greek [22]

Answer:

1 - The problem here is that the existing supplier is not able to supply the required material due to supply constraints. In this condition, there are two options available to the Clayton, as follows

a) End relations with Sarah and look for other suppliers. Search for other supplier who can supply material within the desired duration. This can be done through the process of competitive bidding

b) Continue relationship with the existing supplier and search for other suppliers for serving the immediate demand of the fabric.

2- The trade-off for each decision are as follows:

Option 1

a) More options to chose suppliers

b) Potential of choosing a low cost supplier for long term relationships

However, it is a time consuming process and will affect the existing relationship with the current fabric supplier. New supplier carries more risk in comparison to existing suppliers.

Option 2

a) it will maintain the relationship with existing supplier of fabric, as well as fulfill the current demand

b) Work will run smoothly and will strengthen long term relationship with the existing supplier.

However, managing two suppliers will be difficult and time consuming. Since, the quantity will get divided, there will be lesser quantity discounts.

3 - Clayton first ask to Sarah that some other supplier like her that he can found in a day or two, Supply of fabric is essential to complete the order in over the month. He must have to get outside and find another supplier of fabric until Sarah can find fo him.

4 - This case give us a lesson to have adequate supply and to have some optional reliable source to depend on that they could satisfy the urgent need of the raw material and also in-house production that could indeed reduce reliability over the supplier which can be risky in some situation like this.
