Now use the admissions dataset to create the object tmp$,$ which has columns major, gender, key and value: tmp $<-$ admissions $\%>\%$ pivot$\_$longer$($cols $=$ c$($admitted$,$ applicants$),$ names$\_$to $=$ "key", values$\_$to $=$ "value"$)$ tmp Combine the key and gender and create a new column called column$\_$name to get a variable with the following values: admitted$\_$men, admitted$\_$women, applicants$\_$men, and applicants$\_$women. Save the new data as tmp$2.$ Which command could help you to wrangle the data into the desired format? tmp$2<-$ pivot$\_$wider$($tmp$,$ names$\_$from $=$ column$\_$name, values$\_$from $=$ key, gender$)$ tmp$2<-$ pivot$\_$longer$($tmp$,$ names$\_$to $=$ "column$\_$name", values$\_$to $=$ c$("$gender$",$ "key"$))$ tmp$2<-$ unite$($tmp$,$ column$\_$name, c$($gender$,$ key$))$ tmp$2<-$ pivot$\_$wider$($tmp$,$ names$\_$from $=$ column$\_$name, values$\_$from $=$ c$($key$,$ gender$))$ tmp$2<-$ unite$($tmp$,$
