2a) Calculate an average and sample standard deviation for theindependent variable (time of heating) and the dependent variable(number of surviving organisms) given the data in the tablebelow.
Time (min) ... Number of Survivors
0.1 ... Â Â 2.01x10^6
7.5 ... 2.95x10^5
15 ... Â Â 8.42x10^4
22.5 ... 2.43x10^4
30 ... 6.99x10^3
2 b) Plot the number of survivors over tie on Cartesian,semi-log and log-log axes using only the data points. Identify theplot that best presents the data. Explain why this plot is better.Add a trend line that presents the data, including an R^2 value andequation.
2 c) Using the prediction equation developed in 2b, estimate thenumber of survivors after heating for 50 minutes. How confident isthis estimate? Why?

2A and 2BFirst I shall plot the graphs in cartesian coordinatesNow in the semilogarithmic scaleNow I shall use logarithm for both the time and the number ofsurvivorsFrom the above three plots we can conclude that the log of thenumber of survivors vs time will be the best plotThe trend line is fitted belowThe R squared value will See Answer
