Question: A 95% confidence interval for the average weight of apples in a particular orchard is found to be (150g, 170g). What does this mean?

a) 95% of the apples in the orchard weigh between 150g and 170g.

b) There is a 95% chance that the average weight of all apples in the orchard is between 150g and 170g.

c) If we repeated this sampling many times, 95% of the calculated intervals would contain the true average weight of all apples in the orchard.

d) The average weight of an apple in the sample is 160g.
