Prоblem 4 (14 pts): It is а well-knоwn fаct thаt chickens tend tо lay fewer eggs as they get older. A researcher collected data regarding the age of chickens (in years) and the number of eggs they laid over the course of a year. They want to be able to predict the number of eggs chickens will lay in a year based on their age. Here are the results for 7 chickens. Age of Chicken (in years) 2 5 6 10 8 4 3 Eggs Laid 248 219 202 150 187 220 227 (1 pts) Find the correlation coefficient between age of a chicken and eggs laid. (3 pts) Determine whether a linear relation exists between the two variables. (2 pts) Find the least squares regression line. (5 pts) Interpret the slope and y-intercept of the least squares regression line if it makes sense to. (3 pts) Predict the number of chicken eggs that should be laid in by a chicken that is 7 years old. Is this a good prediction? Briefly explain. Critical Values for Correlation Coefficient n Critical Value 3 0.997 4 0.950 5 0.878 6 0.811 7 0.754 8 0.707 9 0.666 10 0.632 11 0.602 12 0.576 13 0.553 14 0.532 15 0.514
