This corresponds to a two-tailed z-test for proportions. The z-statistics is computed by the following formula:

In our analysis, we compared the profits earned by 60 Crusty Dough Pizza Company restaurants to factors associated to their menu, amenities, services, and statistics regarding the restaurant communities. The factors that we analyzed are listed in Table 1.

“t” is the trial’s number and C is another constant. The C value we use is the average C value of each date point C=0.1925. So z=0.1925*e^(1.0844*t)

The customers in this case study have complained that the bottling company provides less than the advertised sixteen ounces of product. They need to determine if there is enough evidence to conclude the soda bottles do not contain sixteen ounces. The sample size of sodas is 30 and has a mean of 14.9. The standard deviation is found to be 0.55. With these calculations and a confidence level of 95%, the confidence interval would be 0.2. There is a 95% certainty that the true population mean falls within the range of 14.7 to 15.1.

In utilizing hypothesis testing, BWI’s ad campaign that states the average airfares from BWI are lower than averages fares from Dulles. The average (one-way) fares from Dulles over comparable routes is claimed to be $165. If there is a 10% level of significance with over 100 degrees of freedom, there is evidence that the mean sale price is actually not less than those at Dulles. In Figure 1, the t score equals -1.47. Therefore, the null must be rejected because the absolute value of T (1.47) is greater than T of alpha (1.28) for the upper-tail test. The Dulles average fare of $165 is greater than the average fares of BWI of $158.33 (from Figure 2). Average fares at BWI are actually less than the fares at Dulles. Thus, because the null is rejected, there would be a Type I error. If the null is rejected, but BWI accepts the null as true, then the Type I error would prove problematic.

The simulation had shown my ice cream store made a $1.6million revenue with a net profit of $465k. It does not seem very much net profits because of IceFlake’s operating expense in its programs and advertisements. During the operation, 10 employees were hired for IceFlake with a salary that is in the range of $7-9 dollars per hour. Payroll usually consist one of the highest expense in most industry, however the programs at lv10 costed more than the payroll. Furthermore, it is hard to determine rather how effective the programs are at different levels. Even through my market share is averaged at 20% against other 4 competitors, the advertisements provided an unknown amount of how many more customers can be attracted with. The brand recognition was high with customer satisfaction and employee morale at very pleased, but with decreased advertisements shown same number of customers each day. The simulation did not provide a more accurate data or a benchmarking to other competitors, it simply shown how much market share and their price. Therefore, the effectiveness of the programs and its advertisements was difficult to be determined.

Z-test is a statistical way of identifying how certain values or scores differ from the average of two categories that are being looked at in a large sample size. Z-test follow a normal distribution and best to be used with a sample that exceeds 30 and uses proportions for each group. With such test, the null and alternative hypothesis should be stated and the findings reported based on the hypothesis that is accurate either the null or alternative hypothesis.

Exhibits 6, 8, 9, and 10 provide a great deal of information to TruEarth Pizza, including several necessary areas of continuing product development. Creating more appealing varieties and finding a way to increase the convenience factor, for example, would be excellent ways to improve customer response to the product. There are other, more distressing problems that suggest the entire model might be flawed and ultimately unprofitable: two of the most substantial dislikes of the

Slide 3: A Z-score informs us if a variable’s score or value is equal, below, or above the mean. It also determines the exact proportion or percentage of scores that fall between any two scores of normally distributed scores. This sounds similar to the standard deviation; however, standard deviations are set values that fall on a distribution; whereas, Z-scores or values may lie anywhere on the normally distributed curve. Hold that thought and I will go into greater detail as we progress.

Rounding down, we will use a t distribution with 87 degrees of freedom. From the t table we see that t = -2.41 corresponds to a p-value between .005 and .01.

We can analyse from exhibit 13,14 & 15 , that kit has huge potential of attracting customer

– (The above are two ways to write the same equation, the first allows you to calculate z from Q and the second lets you calculate Q from z.) – Look up Prob{the outcome of a standard normal is z or lower} in the Standard Normal Distribution Function Table. utdallas.edu/~metin

Exhibit 15 displays potential change in pizza buying habits after introduction of Contadina Pizza into the market. This data reveals that future pizza kit sales would come from customers who prefer takeout, frozen and fresh pizza from supermarket. Howerver, the largest segment of customer is those that prefer takeout. This segment accounts for 61% of respondents that would try Contadina Pizza on future pizza eating ocassions. The next segment of customers who would purchase Contadina Pizza in the future are those that prefer frozen pizza from a super market. This segment accounts for 25% of respondents that would purchase Contadina Pizza.

To remain competitive in this market segment, businesses must focus on satisfying customers, while providing a quality product. Pizza USA customers have communicated that they would purchase more pizza if a delivery service were offered by the restaurant chain. If the process is well designed and fits the specifications of management, implementing a delivery service to satisfy customer wants would grow the business and increase competitiveness. From a management perspective, research must be done to properly align costs with the return on investment. Many factors must be taken into consideration and the benefits must be measurable. As a customer, we will explore the attributes that make having a delivery service a valuable commodity. Restaurant chains are directly affected by fluctuating economic conditions, which influence customer buying behaviors. Re-branding or re-inventing their image can provide huge advantages for both Pizza USA and the customer. Additionally, by building on the technology now available, the chain can also enhance the customer experience with more ordering options and less error.

This document explains why TruEarth, maker of gourmet pastas, sauces and meals, takes "to launch or not to launch" decision of a new product line of fresh whole grain pizza by using some forecasts and financial analysis. According to the analysis, launching the new product line is a profitable business and it exceeds the minimum business requirements which is $18,5M retail market ($12M wholesale) but according to the market researches, customers think that the product is too expensive and it should be lower. So, after revising its price and sales forecasts, TruEarth should reevaluate the case.
