I really need help. The question is as followed
Eva grows strawberries on her farm
She has this information about the total weight of strawberries grown from 2014 to 2018
Table; 2014. 2015. 2016. 2017. 2018.
Weight/ 105. 104. 102. 90. 83.
Each year there was 200 strawberry plants on the farm
Eva thinks that the mean weight of strawberries grown per plant in a year is between 2/5kg and 1/2kg from 2014 to 2018
Is Eva correct?
Also, why should Eva not use this mean for her estimate of strawberries she will grow in the next year?
