please help me residual data points teacher is a no go A theme park uses roller coaster riders on the “chute” as a predictor of the total number of visitors to purchase a souvenir when leaving the park. There were 232 riders on the “chute” on a Saturday. The statistical analysis predicted that there would be 200 riders. Calculate the residual for that data point I don't see how to solve it's like I have information missing but this is the entire question I have even asked my teacher. She just told me what I need is here and to follow the steps in order find the residual data points but how I can't even get the liner model

The residual is the observed minus the expected, in this case $232-200=32$

You can't get a linear model until you have a load more data
