Final answer:
The weights of jars of jam and the weight of the strawberries used to make jam are quantitative continuous data, while the number of strawberries and jars of jam produced are quantitative discrete data.
Step-by-step explanation:
a) The weights of jars of jam is quantitative continuous data because you measure weights as precisely as possible. For example, you can have a jar of jam that weighs 8.2 ounces or 9.7 ounces.
b) The weight of the strawberries used to make some jam is also quantitative continuous data. You can measure the weight using a scale and get values such as 2.5 pounds or 3.1 pounds.
c) The number of strawberries used to make some jam is quantitative discrete data. You count the number of strawberries, which can be a whole number like 10 or 15.
d) The number of jars of jam produced is also quantitative discrete data. You count the number of jars, which can be an integer value like 100 or 200.
