Consider the model w$=$$1+$$2$e$+$$3$o$50+$u$,($w $=$ beta$1+$ beta$2$ e $+$ beta$3$ o$50+$ u$)$ where w is the natural logarithm of hourly wage, e is the education level $($in years$),$ o$50=1$ if the person is more than $50$ years of age, and o$50=0$ if the person's age is $50$ years or less.

After fitting the model, the researcher obtained beta$3^$Hat $=-0\mathrm{.}1.$ What is the most appropriate comment on this estimate of $-0\mathrm{.}1?$

Group of answer choices

There is age discrimination; for people over $50$ years old, their wage is expected to be $10\%$ lower than people aged $50$ or lower, ceteris paribus.

None of the above.

There is age discrimination; the impact of education on wage is $10\%$ less for people older than $50,$ ceteris paribus.

There is age discrimination, which means that as you get one year older $($o$50$ increase by $1$ unit$),$ your wage is expected to decrease by about $10\%,$ ceteris paribus
