Question

2. Recently, researchers claimed that there is an association between the zone that a piece of land in an inter-tidal shoreline is located in and the abundance of a common gastropod, Bembecium, on that land. To study their claim, the researchers took two SRS’s of 0.25-acre plots of land, one SRS in each of two different types of zones in an inter-tidal area. They counted total the number of Bembecium on each 0.25-acre plot in both of their samples. What is the most appropriate test to analyze this data?

   1. Either One Sample T test or conditions not satisfied.

   2. Either Independent samples T test or conditions not satisfied.

   3. Either Paired T test or conditions not satisfied.

   4. Either Two Proportion Z Test or conditions not satisfied.

   5. Either Simple Linear Regression or conditions not satisfied.

Answer 1

Either Simple Linear Regression or conditions not satisfied.

because here researchers claimed that there is an association between the one independent variable and one dependent variable. this to two variables are as follows,

1) the zone that a piece of land in an inter-tidal shoreline is located in and

2) the abundance of a common gastropod, Bembecium, on that land.

Thus researcher in interested in assocition between two variable. for that purpose, we are using Simple Linear Regression.

also all other given test are used to test the hypothesis about the mean.

hence, correct option is  

Either Simple Linear Regression or conditions not satisfied.
