The population of interest is the pieces of fruit we are using. The fruit is what we are experimenting on. Experimental Design-
For our experiment, we chose three types of fruit to put into the three different wrappings. We did this so that we could have replication. The fruits we used were strawberries, apples and bananas.

We put the fruit in at 7:30 PM Tuesday the 16th and took the fruit out of the fridge at 7:30 PM Tuesday the 23rd. We incorporated the Block Design. We have the same experiment going on with fruit and wrapping, the only difference is it’s broken down into three groups for the three different fruits.
