estimate how sales are influenced by the price of their product. To do so‚ the company randomly chooses 6 small cities and offers the candy bar at different prices. Using the candy bar sales as the dependent variable‚ the company will conduct a simple linear regression on the data below: Prics ($) | Sales | 1.30 | 100 | 1.60 | 90 | 1.80 | 90 | 2.00 | 40 | 2.40 | 38 | 2.90 | 32 | | | What is the estimated slope (b1 for this data set? 161.3855 0.784 -0.3810 -48.193 POINT

Non-repudiation It refers to one of the properties of cryptographic digital signatures that offer the possibility of proving whether a particular message has been digitally signed by the holder of a particular digital signature’s private key. A digital signature owner‚ who may like to deny a transaction maliciously‚ may always claim that his or her digital signature key was stolen by someone and that someone actually signed the digital transaction in question‚ thus not accepting/denying the transaction
