Case study: performance lawn equipment
In reviewing your previous reports, several questions came to Elizabeth Burke�s mind.
Use point and interval estimates to help answer these questions.
- What proportion of customers rate the company with �top box� survey responses
(which is defined as scale levels 4 and 5) on quality, ease of use, price, and service
in the 2012 Customer Survey worksheet? How do these proportions differ by geographic
region? - What estimates, with reasonable assurance, can PLE give customers for response
times to customer service calls? - Engineering has collected data on alternative process costs for building transmissions
in the worksheet Transmission Costs. Can you determine whether one of the
proposed processes is better than the current process?

Question 1
The question requires knowing the proportion of customers who rated the company at top
box scale. From the data presented in appendix 1, in 2012, the customers who rated the company
as per the survey scale 4 were found to be 34 and those who rated the company at survey scale 5
were found to be 15 out of a sample size of 60 customers. this data was collected from north
America.in south America, out of a sample scale of 30 customers,11 customers rated the
company a survey scale 4 and 14 people rated the company at survey scale 14.in Europe,
according to the 2012 customer survey worksheet, out of a sample size of 25 people 15
customers rated the company at a survey scale of 4 and 7 people rated the company at a survey
scale of 5.in pacific rim, the 2012 survey worksheet showed that out of a sample size of 6
customers,3 people rated the company at a survey scale of 4 and only 1 customer rated the
company at a survey scale of 5.in china only one person responded to the survey in 2012 and no
body rated the company in either survey scale 4 or 5.from this survey it is clear that from the
geographic point of view, many customers from the north and South America are more satisfied
by the services of the company compared to the customers from the pacific rim and we have very
few people from china who satisfied by the services of the company.
Question 2
Case study: Performance lawn equipment 3
In the year 2013, the company estimated that in average 3.70944 clients were given quick
response time by the company while in 2014, 3.1136 customers in average were given fast
response time by the company.
Question 3
The proposed plants for mowers according to the transmission cost worksheet was found
to be high than the existing plants since the proposed plant could transmit the mowers at a cost of
$1.40 and the existing plants could transmit at a lower cost in all quartiles compared to the
proposed plants.in addition the proposed plants had high fixed costs compared to the current
plants. This means that the proposed locations were more expensive as compared to the current
locations as per the transmission worksheet.
