Answer:
a) For this case the normal probability plot is on the figure attached.
As we can most of the values are on the straigth line and all are within the confidence bounds so we can conclude that the data does saty relatively close to the reference line.
b) The given data (does) provide significant evidence to claim that it did not come from a normal distribution.
c) As we can see using the figure and with the Anderson Darling test we can conclude that the data can be considered as normal.
Step-by-step explanation:
Part a
For this case the normal probability plot is on the figure attached.
As we can most of the values are on the straigth line and all are within the confidence bounds so we can conclude that the data does saty relatively close to the reference line.
Part b
As we can see on the figure attached the value for the Anderson Darling statistical calculated was:
AD=0.28
And the p value associated was [tex] p_v = 0.541[/tex]
If we use a significance level of [tex]\alpha=0.05[/tex] for example we see that the [tex] p_v >\alpha[/tex] sp then we can conclude that the data follows a normal distribution and the best conclusion is:
The given data (does) provide significant evidence to claim that it did not come from a normal distribution.
Part c
As we can see using the figure and with the Anderson Darling test we can conclude that the data can be considered as normal.
