A data analyst writes the following code in a script and gets an error. What is wrong with their code?

penguins $\%>\%$

filter$($flipper$\_$length$\_$mm $==200)\%>\%$

group$\_$by$($species$)\%>\%$

summarize$($mean $=$ mean$($body$\_$mass$\_$g$))\%>\%$

$1$ point

They are using too many functions.

The first line should have a pipe operator before penguins.

The last line should not have a pipe operator.

They are using the wrong characters for the pipe operator.
