Q$1.$ In a study reported in the Journal of Small Business Management, self$-$employed individuals were asked to report their degree of job$-$related stress. They were asked $15$ questions about their work and they responded on a $1-5$ scale as the amount of stress they felt. These responses were added up in order to come up with a numeric measure of job stress $(15$ being the minimum stress and $75$ the maximum stress$).$ Below is the data for $3$ of the groups: Real Estate Agent, Architect and Stockbroker.

What can we conclude regarding differences in the stress levels for the three groups? Use $=0\mathrm{.}05.$ Generate ANOVA table.
