Question

In a study of feeding behavior, zoologists recorded the number of grunts of a warthog feeding by a lake in a 15 minute time period following the addition of food. The data showing the weekly number of grunts and the age of the warthog (in days) are listed below. Compute the sum of the squared residuals of the least squared line for the given data Week 1 Number of Grunts 90 age(days) 125 Week 2 Number of Grunts 68 age(days) 141 Week 3 Number of Grunts 39 age(days)155 Week 4 Number of Grunts 44 age(days)160 Week 5 Number of Grunts 63 age(days) 167 Week 6 Number of Grunts 40 Age(days) 174 Week 7 Number of Grunts 62 Age(days) 183 Week 8 Number of Grunts 17 Age(days) 189 Week 9 Number of Grunts 20 Age(days) 195 Can you please show me how to do this by hand I am not allowed to use a scientific calculator?

Answer 1

Answer:

Tabulate with the following headings; hence total number of the Grunts is 443
