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

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

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.

And also all the points are very close to the line constructed in the plot and so the data shows Normality.

To evaluate the success of a 1-year experimental program designed to increase the mathematical achievement of underprivileged high school seniors, a random sample of participants in the program will be selected and their mathematics scores will be compared with the previous year’s statewide average of 525 for underprivileged seniors. The researchers want to determine whether the experimental program has increased the mean achievement level over the previous year’s statewide average. If alpha=.05, what sample size is needed to have a probability of Type II error of at most .025 if the actual mean is increased to 550? From previous results, sigma=80.
