**Stratified Sampling of Forest Areas in the Amazon Basin**Stratified samples are effective for studying large forest areas. In this study, satellite images revealed a forest area in the Amazon basin divided into 14 types. The focus was on four commercially valuable forest types: alluvial climax forests of quality levels 1, 2, and 3, and mature secondary forest. These areas were divided into parcels at random, with tree species counted in a specified rectangular area within each parcel. Here's the breakdown:| Forest Type | Parcels | Sample Size ||-------------|---------|-------------|| Climax 1 | 36 | || Climax 2 | 72 | || Climax 3 | 31 | || Secondary | 42 | |The goal is to select a stratified sample of \( n = 18 \) parcels. Address the following:(i). **Parcels to Sample from Each Stratum**:Determine how many parcels to sample from each forest type (stratum).(ii). **Random Sample Selection**:Utilize the following random digits to select a simple random sample of the size determined in part (i), within stratum Climax 1, without replacement. Explain how labels are assigned to parcels, and identify the selected parcels.Random Digits: 69051 64817 87174 09517 84534 06489 87201 97245This exercise demonstrates practical applications of stratified sampling, ensuring diverse representation across different forest types.

There are 4 strata namely Climax 1, Climax 2, Climax 3, Secondary. Each strata has units in parcels.…

The data below lists states poverty rate, gun deaths per 100,000 people, high school graduation rate and the unemployment rate. Use a 2x2 contingency table for questions 1-3. Use the median to divide each list into 2 groups. 1) Test for independence between poverty rate and gun deaths. 2) Test for independence between high school graduation rate and gun deaths. 3) Test for independence between unemployment and gun deaths. 4) Divide the data into 3 groups by gun deaths: 0-9, 9.1-12 and 12.1-20. Use ANOVA to test the claim that the average poverty rate is the same for the three groups. Be sure to write down the mean and standard deviation for each group. 0-9 9.1-12 12.1-20 n = x = s = n = x = s = n = x = s =
