Cbesta Research

I. Introduction

The researchers would like to research about the different companies that offer toothpaste to the market. These toothpaste brands were narrowed down to three brands: Colgate, Close-Up, and Hapee Toothpaste. The researchers would also like to know about the market shares for these companies in the Philippines. The expected market share for these brands are as follows: Colgate (70%), Close Up (20%), & Hapee(10%). The null hypothesis states that the expected market of the three brands of toothpaste are correct while our alternative hypothesis would state that the expected market shares of Colgate, Hapee, and Close up are not correct and have different market shares. To do this, we will use the Goodness of Fit test to understand whether to accept the null hypothesis or to reject it. A survey was also conducted for fifty people to have variables needed for the computation.

II. Methodology

The researchers used the Goodness of Fit test to understand and solve the problem about the different market shares of the companies. The researchers also conducted surveys to better understand the present market and to have data to compare with the expected market share of the companies. There are fifty respondents that were asked to have the data that will be presented in the paper.

III. Case Study

i. Problem

Three Toothpaste Companies: Colgate, Close Up and Hapee have the expected market share of the following Colgate (70%), Close Up (20%), & Hapee(10%). A new product from one of the companies (Close Up) has just been released in the market (Close Up Fire- Freeze) and the researchers would want to know if the market shares have been changed due to this.

ii. Computation

Ho: The proportions (market share) are the same after the brand Close Up introduced their new product into the market, the Close Up Fire Freeze Toothpaste.

Ha: The proportions (market share) are not the same after the brand Close Up introduced their new product into the...
