Answer:
b. Sales promotion 
Explanation:
Sale promotions are activities that a company engages in to persuade a potential customer to buy its products. Sale promotions  are short-term tactics to boost sales.  Although a business may get long-term customers through sales promotions, there are designed to entice new customers in the short-run.
Sales promotions encourage customers to switch brands or try out a different product. They are ideal when introducing new products in the market. Howerver, they are costly, and sometimes have a short term effect on sales. 
This case uses a free sample technique ( free dog biscuits) as the promotion method. Other ways of conducting sales promotions include discount vouchers, free money coupons, and competitions.

The standard deviation of sample equals: 11
Explanation:
Given: 
                                  variance of sample ( ) = 121
) = 121
                                  no, of observations made = 441
                                          standard deviation = ?
By using the formula:
                            Standard deviation (S) = 
                                                                  = 
                                                                  = 
                                                                  = 11
Hence the standard deviation is equal to 11.
