Question

Assume that we are interested in the average length of 1015 fishes in Square Lake, WI. Also assume that all information for all 1015 fishes in this lake is known. Suppose, the average length of all 1015 fishes in Square Lake is 98.06 mm. Derek randomly selects 50 fishes from the Square Lake and obtains and average length of 101.04 mm. Using this information, describe the Individual, Variable, Parameter and Statistic.

Answer 1

Answer is given below

Explanation:

given data

average length of all 1015 fishes = 98.06 mm

randomly selects 50 fishes average length = 101.04 mm

solution

• When we get here, we mean to measure, so here we measure a fish in a square lake.
• And the variable means that a fish varies from fish to fish, so the length of the fish in the squares
• parameter mean that all individuals in the population so the parameter is average length of all 1015 fish in square lake
• statics is selct of individual in sample so statistic is average length of random sected so fish in square lake
