Question

You have done a market research study for a local restaurant by surveying 50 customers. You asked several Likert-type scaled questions, requesting level of agreement with a series of statements (where 1 = completely disagree and 7 = completely agree). These questions include:

X1: I liked the food at the restaurant. (respond on a 1-7 scale)

X2: I liked the service at the restaurant. (respond on a 1-7 scale).

Your results are in the Excel spreadsheet “Customer Satisfaction Study Part 1.”

You think there might be a difference between how much people like the food and how much they like the service and you will do a statistical analysis to see if the difference is significant.

Part 1--State the null and alternate hypotheses in plain English sentences (not equations).

Part 2--Using Excel or any statistical package you are familiar with, do the appropriate statistical analysis to determine if these two variables are significantly different from each other. Clearly justify your choice of statistical analysis. Print out the computer results.

Part 3--Can you reject the null hypothesis? Why or why not? Make a brief recommendation to management based on your findings.

Answer #1

Null Hypothesis H_{0} : The liking for food and service
are independent (i.e) correlation coefficient=0

Alternative Hypothesis H_{1} :The liking of food and
service are dependent (ie)correlation coefficient

Level of significance = 0.05

Since it is a ordinal data ,we may use of Spearmen rank
correlation coefficient,r_{s} = .077

To test for significance of r_{s} ,t test is used .

The p value is .594

Since p value > 0.05 ,we accept null hypothesis and we can conclude that the liking of food and service are indepenfind and the recommendation is that the restaurant can continue their services without depending on one and another

A restaurant is experiencing discontentment among its customers.
The feedback revealed that there are three factors responsible; F1:
food quality, F2: service quality and F3: interior décor. By
conducting an analysis, it assesses the probabilities of
discontentment (D) with the three factors as 0.40, 0.35 and 0.25
respectively. By conducting a survey among discontented customers,
the probabilities of a customer going away discontented given these
factors are 0.6, 0.7 and 0.5 respectively. The restaurant wants to
know that if a...

1. Consider a survey in which customers’ perceptions of the
service at a local store are gathered using a Likert Scale. Using
this survey the customer gives a score of 1, 2, 3, 4 or 5 in
response to a statement about the service.
The scores represent
1 – Strongly Disagree
2 – Disagree
3 – Unsure
4 – Agree
5 – Strongly agree
For example, one of the statements might be “The staff member
appears knowledgeable regarding the store’s...

Suppose 50 people come to a fast food
take-out
restaurant each hour. There are four employees, one
at
the register, two making the food, and one packaging
the
food. Suppose on average, each order takes 30
seconds
at the register, and it takes one employee an average
of
1.5 minutes to make the food, and it takes 1 minute
on
average to package the food. Assume exponential
arrivals
and service times.

You’re thinking about opening up a restaurant in your
neighborhood but before you do so, you decide to do a little
research to figure out what your potential market looks like. You
randomly select 10 individuals in your neighborhood and ask them
how many people live in their household (household size) and how
often they dine out each month (restaurant visits). The data you
collected is given in the table below.

You run a game day shuttle service for parking
services for the local ball club. Your costs for different customer
loads are 1: $30, 2: $32, 3: $35, 4: $38, 5: $42, 6: $48, 7: $57,
and 8: $68. What are your marginal costs for each customer load
level? If you are compensated $10 per ride, what customer load
would you want?
