The number of days required for two suppliers to deliver orders is as follows.

Supplier A:	10.0	4.0	13.0	1.0	17.0	7.0	11.0	16.0	6.0	19.0
Supplier B:	9.0	4.0	13.0	2.0	23.0	8.0	12.0	15.0	6.0	24.0

(A) Which supplier provides more consistent and homogenous delivery times A or B? ...

Average Number of Days for Supplier A = days, and Standard Deviation = day.

Coefficient of Variation for Supplier A =

Average Number of Days for Supplier B = days, and Standard Deviation = day.

Coefficient of Variation for Supplier A =

(B) Justify your answer? ...

Since the (Click to select) Coefficient of Variation Mean Standard Deviation Variance of (Click to select) Supplier A Supplier B is less than that of (Click to select) Supplier B Supplier A , then it is more consistent and homogenous delivery times.

Solutions

Expert Solution

(A).

Supplier A:

The sample mean is,

The sample standard deviation(s) is,

The coefficient of variation (c.v.) is,

Average Number of Days for Supplier A = 10.4 days, and Standard Deviation = 5.929 days.

Coefficient of Variation for Supplier A = 0.5701

Supplier B:

The sample mean is,

The sample standard deviation (s) is,

The coefficient of variation (c.v.) is,

Average Number of Days for Supplier B = 11.6 days, and Standard Deviation = 7.4416 days.

Coefficient of Variation for Supplier B = 0.6415

(B).

Since the Coefficient of Variation of Supplier A is less than that of Supplier B, then it is more consistent and homogenous delivery times.

An online retailer of small gifts orders products from a number of suppliers, stores them, packs them to customers’ orders, and then dispatches them using a distribution company. Although broadly successful, the business is very keen to reduce its operating costs. A number of suggestions have been made to do this. There are as follows: Quality: Make each packer responsible for his or her own quality. This could potentially reduce the percentage of mis-packed items from 0.5% to near zero....
