data1<-district %>% select(DISTNAME, DPETSPEP, DPFPASPEP)

The missing values are in DFPASPEP

data2<-data1 %>% na.omit()

There are 1,202 observations remaining in data2

cor(data2$DPFPASPEP, data2$DPETSPEP)

## [1] 0.3700234

In our data set we observe a week correlation between the spending on special education and the percent of students in special education.
