I was wondering what R code would be used in this situation. This problem is based on an SLR (model.lm=lm(api00~meals, data=elemschools)).

Consider the Elementary Schools in California data set from Homework 1'. It contains a measure of school academic performance as well as other attributes of the elementary schools. (A detailed data set descrip tion can be found below). In this problem, our goal is to study the relationship between the API of the school in 2000 (variable: apiOO) and the percentage of students who receive free meals (variable: meals). Use R and R Markdown to answer the following questions: (a) Estimate the difference in the mean apiOO score for two schools whose free meals differs by 1. Use a 90% condence interval
