I am trying to write a code in R and have come to this question I cannot figure out what I am doing wrong

Explore the relationship between the number of applicants $($App$)$ and the number of acceptances $($Accept$).$

Use lm to obtain a best fit linear model for Accept $($y$-$variable$)$ based on App $($x$-$variable$).$

# Obtain the best fit linear model for Accept $($y$-$variable$)$ based on App $($x$-$variable$)$

lm$\_$model $<-$ lm$($Accept ~ App, data $=$ College$)$

# Correlation coefficient

correlation$\_$coefficient $<-$ cor$($College$Accept, College$App$)$
