Question

Find the mean of 5, 6,17, 8, 9, 15, 23,18,10 & 24. Also find

the resulting mean, If each observation decreased by 2.​

Answer 1

Answer:

The mean for 5,6,17,8,9,15,23,18,10,24 will be 13.5.

Step-by-step explanation:

Mean is another word for average. So the average of all the numbers will be 5+6+17+8+9+15+23+18+10+24 = 135/10 = 13.5

Next it asks for the resulting mean if each observation is decreased by 2.

Which means,

(5-2)+(6-2)+(17-2)+(8-2)+(9-2)+(15-2)+(23-2)+(18-2)+(10-2)+(24-2) = 115/10 = 11.5

Hence the mean for this will be 11.5

Hope this helps :)
