Question

Find the mean of the following distribution
​

Answer 1

Answer:

x=15

y=8

Step-by-step explanation:

x= sum of all observations/no of observations

x=5+10+15+20+25/5 = 15

y = 2+8+15+10+5/5 = 8

Answer 2

Answer:

mean = 75

Step-by-step explanation:

We know that,

$mean = \frac{ \sum \: fixi}{ \sum \: fi}$

$mean = \frac{40 \times 75}{40}$

$mean = \frac{300 \not0}{4 \not0}$

$\boxed{mean = 75}$
