Answer 1

Question

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.

In the question, the data is given that described of the effects of logging on counts in the Borneo rainforest as:

Group 3
18
4
22
15
18
19
22
12

Thus, firstly we will sort the data from smallest to largest by using excel. That is first we will select the data and click the sort and filter option and then select ascending order. Thus, the result will be as:

Group 3
4
12
12
15
18
18
19
22

Now we will use the R programming to construct the Normal quantile plot and scatterplot by using the codes as:

G=c(18,4,22,15,18,19,22,12,12)z=qnorm(((1:9)−0.5)/9)library(plotly)data=data.frame("No_of_trees"=G,"Normal_scores"=z)figg=plot_ly(data=data,x=~Normal_scores,y=~No_of_trees)figgplot(x=z, y=G,col="red",xlab="Normal_scores",ylab="No_of_trees",main="Normal Quantile Plot")qqnorm(data$No_of_trees,pch=1, frame=FALSE)qqline(data$No_of_trees,col="blue",lwd=2)

And the plots are as:

The above plot is Normal quantile plot which shows the Normality of the data and in this we can see that the points are approximately in a straight line and increasing.
