The data file can be found in Moodle under the “Data Sets” portion of the “Misc” section. It is named Trademarks 1.1 Getting Started 1.1.1 Motivating Question In 1.1, we will try to answer the question: What procedures should be used given the goal in the Introduction for Part 1? 1.1.2 Parameter 1) Describe, in context, the parameter of interest. 2) Describe, in context, the statistic of interest. 3) Give the value of the statistic.

Answer 1

1.1.2

In this question we are given about the the various entities that have been the state of Oregon.

We need to find the proportion of the registered entities which are from OR.

For we check the STATE column in the data, and count all the number of times OR occurs

We see that 57 out 75 registration are from OR.
Hence the proproption is 57/75 = 0.76

1. Parameter of interest - In all the entities registered in state of Oregon, the proportion of the registered entities which are from OR

2. Statistics of interest - In the given sample proportion of the registered entities which are from OR

2. Statistics = 0.76

1.1.3

For this question we need to test the hypothesis if more than 80% of active registered trademarks in the state of Oregon are from state of Oregon or not.

Hence we need to use a one sample proportion ztest to test the hyothesis. THe hypothesis is shown in detail below.

Hence there is no sufficient evidence to support the claim that more than 80% of active registered trademarks in the state of Oregon are from state of Oregon
