Answer 1

Answer:

Given height of 8 students = 180cm , 160cm , 175cm , 165cm , 178cm , 170cm , 174cm and 182 cm

We already know that mean is equal to sum of all data points by the number of all data points, So,

⇒ Mean of their heights = $\frac{180cm + 160cm + 175cm + 165cm + 178cm + 170cm + 174cm + 182cm}{8}$

⇒ Mean of their heights = $\frac{1384}{8}$

⇒ Mean of their heights = 173cm

Thnx and have a nice day!
