Regression Analysis: EMISI versus JARAK TEMPUH
The regression equation is
EMISI = 314 + 6.88 JARAK TEMPUH

KESIMPULAN :
1. jarak tempuh berpengaruh positif( regresi b=6.88) terhadap emisi, maka semakin tinggi jarak tempuhnhya, semakin besar j
uga emisinya.
2.emisinya =314, apabila jarak tempuhnya 0 maka emisinya 314.
