4. Misol ishlash
Quyidagi 10 ta kichik korxonada ishlab chiqarilgan mahsulot va sarflangan yoqilg’i haqida ma’lumotlar keltirilgan:

Ishlab chiqarilgan mahsulot, ming dona	5	6	8	8	10	10	14	20	20	24
Sarf qilingan yoqilg’i, tonna	4	4	6	5	7	8	8	10	12	16

Jadvalda keltirilgan ma’lumotlarga asosan ishlab chiqarilgan mahsulot va sarflangan yoqilg’i o’rtasida bog’lanishni to’g’ri chiziqli tenglama orqali tasvirlang. Olingan regressiya tenglamasini mohiyatini tushuntirib bering.
