Advertising expenditures and sales for the last 5 quarters have been as follows:

In quarter 3, a new product was introduced that would influence sales in quarter 3. 4 and 5. The following model is established:

y=β₁x₁+β₂x₂+ ε

where y=sales, x₁=advertising expenditures, x₂ is a variable that is 1 when the new product is available and 0 otherwise, and ε is an error component. Find the least squares estimate of β_1.

Write LISP functions GEFILTER and LFILTER. GEFILTER takes a numeric atom and a list of numbers and returns a list consisting all numbers in the list which are greater than or equal to the given number. LFILTER takes a numeric atom and a list of numbers and returns a list consisting of all numbers in the list less than the given number. For example: (GEFILTER 4 ‘(3 5 8 2 4 1 9)) Returns the list (5 8 4 9) and (LFILTER 4 ‘(3 5 8 2 4 1 9)) Return the list (3 2 1)

Provided that c1, c2 and c3 are of appropriate ranges. Use transform() algorithm so that it copies the larger of the corresponding elements from c1 and c2 to c3. That is, if

   c1 = {1, 2, 3, 4, 5} and   c2 = {5, 4, 3, 2, 1}

   then c3 should become c3={5, 4, 3, 4, 5}

A combinatorial auction allows participants to make bids on items in either individual or grouped quantities. Suppose an auctioneer has 4 items. There are 6 bidders who bid the following:

Bidder 1: $6 for item 1

Bidder 2: $3 for item 2

Bidder 3: $12 total for items 3 and 4

Bidder 4: $12 total for items 1 and 3

Bidder 5: $8 total for items 2 and 4

Bidder 6: $16 total for items 1, 2, and 4

Each item can only go to at most one participant. If a bidder won the bid on multiple items, they must receive all of them.

formula a linear Integer Program that helps the auctioneer maximize revenue. Clearly define all decision variables and constraints.

A sequential game with two-players 1 and 2, where player 1 has the first move advantage. Each player has two strategies, A and B. If both players choose A, each gets a payoff of 2. Both choose B, each gets a payoff of 3. For player 1 choose A and player 2 choose B, player 1 gets 4, and player 2 gets 1. If player 1 chooses B and player 2 choose A, player 1 gets a payoff of 1, and player 2 gets 4. How many, if there is any, subgame perfect equilibrium are there?

calculate the mean, median, mode, and standard deviation based on the data provided.
