A scientist wants to know if there is a meaningful difference between two groups of gels that grow bacteria. He randomly selects six gels from each group, and counts the number of bacteria spots on each gel. Group A: 9, 12, 13, 13, 14, 17 Group B: 8, 6, 5, 8, 13, 8 Is there a meaningful difference between the two groups? Describe or show all calculations that lead to your answer. Pls helppp

no association

step-by-step explanation:

if you have eyes and you can use them efficiently you can see that it just looks like random dots like do a line of best fit and like they're so spread out it's such a weak association you might as well consider it nonexistent

yes

step-by-step explanation:

yes

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system

$15.40 per mile

step-by-step explanation:

you have to round up to 4 because 6 is over 5 so you have to round the 3 up to 4
