SQuestion 1

1. Determine which of the following statements is descriptive in nature and which is inferential. Refer to the data below in How Old is My Fish?

a. All 9-inch largemouth bass in New York State are an average of 3 years old.

Because you used the word 'all,' this is inferential statistics because an inference was made about all largemouth bass in New York State from this data set.

b. Of the largemouth bass used in the sample to make up the NYS DEC Freshwater Fishing Guide, the average age of 9-inch largemouth bass was 3 years.

Because this statement refers to a sample but not all largemouth bass in New York State, and precisely stated that the average age of 9-inch largemouth bass was 3 years come from the sample, this is descriptive statistics.

Question 2

Women (%)

σ= 14.8284; Variance=σ²= 219.8816; σn-1 = 15.1342; (σn-1)²= 229.0433; CV% = 35.9%

Mean(μ)= 41.28; range= 60; mid-range= 40; median= 43; No Mode

Job Growth (%)

σ= 40.5239; Variance=σ²= 1642.1856; σn-1 = 41.3595; (σn-1)²= 1710.61; CV% = 135.6%

Mean(μ)= 29.88; range= 188; mid-range= 95; median= 22; Mode= 1 Probably right skewed.

Training (hr/yr)

σ= 25.4334; Variance=σ²= 646.8576; σn-1 = 25.9579; (σn-1)²= 673.81; CV% = 64.1%

Mean(μ)= 39.68; range= 100; mid-range= 50; median= 40; Mode= 40

I concluded that there are more woman holding jobs. However, there is more Mid job growth with less woman. More woman in median with more mode in job growth.
