Question $2$

Let $x$ be a numeric vector and suppose you want to know how many entries of $x$ are strictly less than $5.$ Create a new variable $y$ which is equal to the number of entries of $x$ that are $($strictly$)$ less than $5.$ For example, if

then your variable $y$ should be equal to $6.$ Your code for $y$ must be expressed in terms of so that for different vectors $x$ the same expression for will always give the correct answer. To do that, we create a function counts $()$ with input argument $x.$ Within this function you need to create your variable $y$ in terms of $x,$ so that this function returns the right answer for any numeric vector $x.$

Also, within the function, create another variable which is equal to the number of entries of $x$ that are strictly between $-5$ and $5.$ Like $y,$ the variable $z$ must be expressed in terms of $x$ so that the same expression for works for various vectors $x.$ The autograder will test your answer for several vectors $x.$

You should have only two lines of code, one for $y,$ one for $z.$ Also, there is no partial credit! $($This is true for each question$).$ If one of the vectors or $z$ is wrong but the other one correct, you still get $0$ pts$.$
