Answer

**(a) Units of Measurement** Valid units for measuring fish weight are ounces and pounds. **(b) Best Procedure** The best way to find the average weight is to randomly select 42 fish from the entire pond and weigh each one.

Solution

**(a) Units of Measurement** The weight of a fish can be measured in units of mass. Among the options provided, the valid units are: - \( \text{ounces} \) - \( \text{pounds} \) The other options (seconds, hours, minutes) are units of time, not weight. --- **(b) Best Procedure** To accurately find the average weight of fish in the pond, the procedure must avoid any bias in the sample selection. The best method is to: - \( \textbf{Randomly pick 42 fish from the entire pond and weigh each of them.} \) This method ensures that the sample is representative of the entire pond population and that the measurements are accurate. ---

Extra Insights

To measure the average weight of fish, the most relevant unit of measurement would be ounces or pounds, as they are commonly used to denote weight. While seconds, hours, and minutes are associated with time, they aren't applicable for measuring the weight of fish. So, stick with the weight units for accurate representation! When it comes to selecting the best procedure for finding the average weight, opting for randomly picking 42 fish from the entire pond and weighing each of them is the way to go! This method ensures a proper representation of the entire pond population, avoiding bias and giving you a more accurate average weight. Estimating weights or picking from just one region could lead to misleading results!
