Biological Variability Fill in Data Table 1 with the number of sow bugs your team observed in the light after the indicated times. Then fill in the deduced number of sow bugs that were in the dark at each of those times. Data Table 1. Sow Bug Team Data (1 pt.) Time in Minutes 0 1 2345 6 7 8910 Trial #1 Number| 5 | 4 | 3 in Dark Number 5 5 in Light Number in Dark Trial #2 Mean Number in Dark Data Table 2 contains data and calculations for a pill bug data set that was previously collected for your use. Use this table to help you complete Data Table 3.

Experin Fill in the second column of Data Table 3 with the class data for the number of sow bugs in the dark after 10 minutes. Complete the rest of the table by performing the indicated calculations Data Table 3. 10-Minute Sow Bug Data (2 pts.) #in Dark at、 Number 10 Minutes (x) Deviations Squared (X,-X)2 Team cumulative Mean | (X,-x) | ユ25 5 1 C 8 9 10 0 12 sow bug mean (x)--. Question 3. (2 pts.) Did your cumulative mean for the sow bugs stabilize at some point in the sampling process? If it did not, in your opinion, why not? If it did, about how many data sets did it take to stabilize? What does this indicate about your original population sample of 12 data sets-was it big enough to get a stable sample mean? Question 4. (7 pt.) The final value in the cumulative mean column is the overall class mean in the dark after 10 minutes. Record this value here: for number of sow bugs
logical Variability Question S. (2 pts.) It is unlikely that the mean you calculated for the class sow bugs is identical to the mean of the pill bug data that was provided. Can you conclude that the two species differ in their response to light based onhy on these mean values? Explain why or why not. Question 6. ( pt.) What is the variance for the 10-minute pill bug data sets that were provided to you? Remember that (variance)s=E(x-x), s-4aga alus4.aa) 34 9) 4.993 Question 7. (7 pt.) What is the variance of your 10-minute class sow bug data set? Question 8. ( pt.) What is the standard deviation of the class sow bug data? s Remember that standard deviation (s)-ty Question 9. (2 pts.) This labs PowerPoint describes an important relationship between the standard deviation and the shape of a normal distribution curve. Specifically, 95% of the samples lie within two standard deviations above or below the sample mean. From the class sow bug data, we can conclude that 95% of the time, between-_ and- _ sow bugs out of every ten would be located in the dark rather than the light mean- 2e meanF20
