A State lottery sells three games: Fantasy 5, Mega Money, and Lotto. Sales (tickets sold, not money) are recorded by district and for weekdays versus weekends.

Assignment Detail
A. Managers think that Lotto is mostly a weekend seller. Create a hypothesis and test it. Explain your results in the online text.

B. Managers suspect that different districts favor different games. Create a hypothesis and test it. Explain your results in online text. Also create descriptive statistics to provide further evidence to compare with the inferential statistics: create a conditional distribution table (week six notes) and/or a bar graph that shows the conditional distribution visually. Explain your results in online text and compare it with the hypothesis test results.

Step-by-step explanation:

The factorization of x² - 5x + 6 can be determined thinking critically about two numbers, that if we multiply those two numbers together it will result into a value of +6 and if we add those numbers together , we will have -5

The numbers are -3 and -2 ; if we multiply -3 and -2 , we have = 6

If we add -3 + (-2) ; we have,

-3-2 = -5

Now the factorization of

x² - 5x + 6 = 0 is as follows.

x² - 3x - 2x + 6

By factorization,

x(x - 3) - 2 (x - 3) = 0

(x - 2) or  (x-3) = 0

Now, using An algebra tile configuration. The diagrammatic expression showing how an algebraic tile configuration should looks like can be found in the attached image below.

Hint:

Let represent ,

1   =   x² tile

-5 = - x tiles

6  =  1 tiles
