SpletWe know that the last three observations are. 9 + 4 = 13. 9 + 6 = 15. 9 + 8 = 17. We know that. Mean of last three observations = (13 + 15 + 17)/3. On further calculation. Mean of last three observations = 45/3. By division. Mean of last three observations = 15. Therefore, the mean of last three observations is 15. SpletMean of 8 observation = 18.5 Formula used: Mean = Sum of observation/number of observation Calculation: Mean = Sum of observation/number of observation ⇒ 18 = Sum of 7 observation/7 ⇒ Sum of 7 observation = 18 × 7 ⇒ Sum of 7 observation = 126 Let 8 th observation be P ⇒ (Sum of 7 observation + 8 th observation)/8 = 18.5 ⇒ (126 + P) = 18.5 …
