I believe number 5 is c and number 6 is f
The given data is
x =[26 32 18 47 16 24 33 17 34 27 24 36 23 26 19 22 21 20 35 28 29 43 23 33]
The sample size is n = 24
min(x) = 16
max(x) = 47
The sorted data is
[16 17 18 19 20 21 22 23 23 24 24 26 27 28 29 32 33 33 34 35 36 43 47]
Part A.
Create a frequency table using a class width of 5.
Class Frequency
---------- ----------------
15 - 19 4
20 - 24 7
25 - 29 5
30 - 34 4
35 - 39 2
40 - 44 1
45 - 49 1
Part B
Create a frequency histogram with bin widths of 5.
The histogram plot is shown below.
Part C.
The distribution appears to a skewed normal distribution.
The mean is skewed toward the lower values of the sample values.
Consequently, the distribution has a short tail for small values of x but a longer tail for larger values of x.
X = cos(pi/6) = √3/2
y = sin(pi/6) = 1/2
So at point (√3/2, 1/2)
