Answer:
2. Find the five boundary values
Step-by-step explanation:
When drawing a dot, the steps are;
i) The data set (the list of numbers to be presented in the dot plot) are arranged in increasing order from left to right, with thee lowest value on the left and the highest value located at the right of the list
ii) The five boundary values are listed as follows;
The Minimum and Maximum Values
1) The minimum value is the lowest number in the list, which is the first number from the left
2) The maximum value is the final number on the right of the list
3) The Median, Q₂
The median number is the number which divides the data arranged in increasing number, into two equal parts
The First Quartile and Third Quartile
The numbers are divided from the median, such that the Lower half is to the left of the Median, and the Upper half is to the right of median
4) The First Quartile, Q₁ = The median of the Lower half
5) The Third Quartile, Q₂ = The median of the Upper half
iii) The box plot is then drawn with the five boundary values found above
Answer:
Step-by-step explanation:
slope intercept form is y = mx + b
b is the y intercept ( crossing y axis value).... by inspection b = -4
m is the slope of the line, Slope = m = 1/4 note: the slope is positive
the slope equals the 'rise' over 'run'
if the line moves up the slope is positive, if the line moves down the slope is negative
the rise is how many y units does the line go 'up' or 'down'
the run is how many x units does the line go 'left' or 'right'
the rise = 1 Y unit
the run = 4 X units
y = mx + b m =1/4 b = -4
y = (1/4)x + (-4)
y = (1/4)x - 4
graph a line stating at y = -4 and going up (rising) to the right ONE Y Unit for every FOUR X units (the run)
Answer: The observed ratio is different from the expected ratio.
Step-by-step explanation:
Since we have given that
Expected ratio :
Ratio of blue flowered plants to white flowered plant = 3:1
Observed results:
Number of blue flowered plants = 35
Number of white flowered plants = 14
So, Ratio of blue flowered plants : white flowered plants
So, 5:2 ≠ 3:1
Hence, the observed ratio is different from the expected ratio.
