Question

data collected during an experiment are shown in the accompanying graph. what is the range of this set of data? 1) 2.5≤y≤9.5 2) 2.5≤x≤9.5 3) 0≤y≤100 4) 1≤x≤10

Explanation:

Step1: Recall range definition

The range of a data - set is the difference between the maximum and minimum values of the variable of interest. In a graph, if \(y\) represents the dependent variable (Percent Maximum Activity of Trypsin in this case), the range is the set of all possible \(y\) - values.

Step2: Identify minimum and maximum \(y\) - values

From the graph, the minimum value of \(y\) is \(0\) (the lowest point on the \(y\) - axis where the curve touches) and the maximum value of \(y\) is \(100\) (the highest point on the \(y\) - axis where the curve reaches).

Answer:

1. \(0\leq y\leq100\)
