Transcribed Image Text:Question There is a relationship between the average age of mothers and the average number of cesarean operations (as opposed to natural) during childbirths in the population of Indian women. The data are as follows: Ave. Age (years) 20 25 30 35 40 45 Ave.no of 51 87 106 219 342 428 cesarean/year
a. For the above data what is the value of "a", intercept ?
What is the value of regression coefficient?
b. Describe the equation that that explains this relationship
c. What are the values of "r" and the r ?
d. Three values of average age you would use for
calculating the line of best fit would be 22, 34 and 43
years. Do vou agree? Give reasons for your answers
