The least-squares line predicting sales from the number of advertisement is:
sales = 105 + 9.3 * advertisement
sales increase by 105 for each additional advertisement
sales increase by 9.3 for each additional advertisement
sales decrease by 105 for each additional advertisement
sales decrease by 9.3 for each additional advertisement
Homework Answers
We have given regression equation is,
sales = 105 + 9.3 * advertisement
slope= 9.3
Therefore,
sales increase by 9.3 for each additional advertisement
Add Answer to:
The least-squares line predicting sales from the number of
advertisement is:
sales = 105 + 9.3...
