Answer 1

1. Answer is

Yes.

To check whether the data appear to be normally distributed we will plot histogram. We will use R software to obtain histogram.

R software codes

>data=c(5.19,1.2,0.5,0.33,0.15,0.15,0.15,0.07,-0.02,-0.02,-0.28,-0.37,-0.46,-1.76,-2.8)

>hist(data)

Data vector is created. hist() function is used to obtain histogram for the data.

R software output

Look at the above histogram. Shape of the histogram is like bell shape which indicates that the data seems to be normally distributed.
