Question

use the class data to graph the lactaid activity at different temperatures. use the average data points for each temperature (you need to have 4 separate lines for each temperature). use the x axis to report the time at which each measurement was taken and the y axis to report the dependent variable (glucose concentration). give your graph a title and label axes, including units.

	0 c	0 c	37 c	37 c	65 c	65 c	100 c	100 c
5 min	500	250	500	500	2000	2000	neg	neg
10 min	250	250	2000	500	2000	2000	neg	neg
15 min	250	250	1000	1000	2000	2000	neg	neg
20 min	1000	500	1000	1000	2000	2000	neg	neg

Explanation:

Step1: Calculate average data points

For each temperature, average the two sets of data at each time - point. For example, at 0°C and 0 min, the average is $\frac{0 + 0}{2}=0$. At 0°C and 5 min, the average is $\frac{500+250}{2} = 375$. Repeat this for all time - points and temperatures.

Step2: Set up the graph

On the x - axis, label the time in minutes (0, 5, 10, 15, 20). On the y - axis, label the glucose concentration. The units for the x - axis are minutes (min) and for the y - axis are the units of glucose concentration (not specified in the problem, assume it's the same as the data values given).

Step3: Plot the lines

For 0°C: Plot the points (0, 0), (5, 375), (10, 250), (15, 250), (20, 750) and connect them with a line.
For 37°C: Plot the points (0, 0), (5, 500), (10, 1250), (15, 1000), (20, 1000) and connect them with a line.
For 65°C: Plot the points (0, 125), (5, 2000), (10, 2000), (15, 2000), (20, 2000) and connect them with a line.
For 100°C: Since all values are "Neg" (negative or non - detectable), we can plot points at the lower limit of the y - axis (assume 0) for each time - point (0, 0), (5, 0), (10, 0), (15, 0), (20, 0) and connect them with a line.

Step4: Give a title

A possible title could be "Lactaid Activity as a Function of Time and Temperature". Label the x - axis as "Time (min)" and the y - axis as "Glucose Concentration".

Answer:

A graph with the title "Lactaid Activity as a Function of Time and Temperature", x - axis labeled "Time (min)" and y - axis labeled "Glucose Concentration", with four lines representing lactaid activity at 0°C, 37°C, 65°C, and 100°C respectively.
