NPTEL Data Science For Engineers Week 6 Assignment Answers 2023

1. What is the relationship between the variables, Coupon rate and Bid price?

  • Coupon rate = 99.95 + 0.24 * Bid price
  • Bid price = 99.95 + 0.24 * Coupon rate
  • Bid price = 74.7865 + 3.066 * Coupon rate
  • Coupon rate = 74.7865 + 3.066 * Bid price
