1. An experiment is conducted to evaluate the storage conditions for fish after it has been caught. Fish were caught and either directly put into a freezer or left out for different intervalst_lag(3, 6, 9, and 12 hours) before being put into the freezer. The bacterial contamination was evaluated after 7 days of storage in the freezer. For every time point, 3 fish were caught and stored accordingly.[10 points]
   1. Plot and calculate the linear regression model for the relationship between time interval between catching and freezing fish (t_lag) and the units of bacterial growth (note:you can use Microsoft Excel or any other program that is able to calculate simple linear regression models. If you do, please provide the data file in addition to the answer).

Bacteria (in units)	Delay time (in hours)
Fish	tlag=0	tlag=3	tlag=6	tlag=9	tlag=12
1	5	23	52	140	162
2	20	41	63	122	185
3	10	39	71	105	166
