Question

You are required to produce two generalizations: (a) the average weight of a hen’s egg and (b) the average weight of a classroom chalk. You want your conclusion to be as systematic as possible with a limited time and with limited materials. How would the two determinations differ in number of observation required? In exactness of hypothesis possible? In difficulty of verification? In exactness in which you may state the average weight?

Thanks!

Answer 1

hen eggs have reasonable sigma.
classroom chalk (I assume we are talking used chalk) has wild variation so would require far more observations and might eventually converge to a mean weight somewhat over half the weight new in the box.
