Answer 2

There is more than one way to determine if there are outliers in data. Do you have "the procedure from the previous question" ?

Answer 3

no because its a different type of question

Answer 4

I usually used this definition:
Large outliers= an observation which is farer than 2.5 standard deviations from the mean.

In this case, st.dev.=2.6 and mean 3.0. moreover, there is an observation=10.5, namely the maximum. since 10.5 is more than 3(2.5x2.6), then we can conclude that 10.5 is an outlier.

Having said that, it should be stressed out that whether an observation is a large outlier or not, is a matter of convention.
