1 and 7 are the answer to this
Answer:
Step-by-step explanation:
5,9,11,(13,16),16,19,21
the mean(middle number) = (13 + 16) / 2 = 29/2 = 14.5
Q1 = (9 + 11) / 2 = 20/2 = 10
Q3 = (16 + 19) / 2 = 35/2 = 17.5
interquartile range (IQR) = Q3 - Q1 = 17.5 - 10 = 7.5 <==
Equation would be: Y = 25 + 5x
Where, x = number of weeks
So, when x = 1, Y = 25 + 5(1) = 25+5 = 30
When x = 2, Y = 25 + 5(2) = 25 + 10 = 35
x = 3, Y = 25 + 5(3) = 25 + 15 = 40
So, Mark the coordinates: (0, 25), (1, 30), (2, 35), (3, 40), (4, 45), (5, 50)...
And draw a line...Graph is done!
Hope this helps!
