Answer 1

Answer:

4. (i) 2,950

(ii) 3,115

Step-by-step explanation:

Dude its very easy....

4. we know, mean = total sum / no. of quantities

(i) hence,

• sum= 1580+2020+2580+3200+3550+3710+4010

= 20,650

• no. of quantities = 7

so,

mean = 20650/7 = 2950

(ii) again,

• new sum = 20650 + 4270

= 24920

• no. of quantities = 8

so,

new mean = 24920/8 = 3115

Hope it helps you buddy....
