4. Misol ishlash
Konserva zavodi ishchilarining ishlab chiqargan mahsuloti va mahsulotni ishlab chiqarish uchun 1 ishchi sarf qilgan kunlik elektr energiya to’g’risida quyidagi ma’lumotlar berilgan:

Har bir ishchining bir kunda ishlab chiqargan mahsulot qiymati, mln. so’m	2,5	3,0	4,5	5,0	5,5	6,5	7,0
Bir ishchining kunlik elektr energiya sarfi, kvt/soat	2,1	2,0	1,9	1,7	1,5	1,4	1,2

Hisoblang:
1) ishlab chiqarilgan mahsulot va sarf qilingan elektr energiya o’rtasidagi bog’liqlik tenglamasini tuzing,
2) korrelyastiya koeffistentini hisoblang,
