a) Determine the dispersion measures: the variance, standard deviation, and COV
b) Plot the histogram for concrete strength and discuss the characteristics.
c) Plot a histogram with the BMI interval of 2.
a) To compute,
Variance =
Standard deviation (s)=
Coefficient of variation = %
Where, = mean =
now, mean= 28.474
Variance = 24.578
Standard deviation = 4.958
Coefficient of variation = (4.958/28.578)*100% = 17.41%
b)Histogram for concrete strength :
The curve follows log normal distribution.
c) Histogram with bmi Interval of 2 :

A researcher intended to investigate the potential difference in BMI between men and women. He also tried to evaluate the effectiveness of a new physical exercise program in reducing BMI. Table 1 summarized the BMI data. At the beginning of the study (Day 0), 64 men and 49 women were included in the study and their BMI values were measured (defined as BMI_M0 and BMI_F0, respectively). After joining the new physical exercise program for 180 days, the participants’ BMI values...
You are required to write a concise report with all your answers in doc or pdf file. You should include tables or figures from Excel in your report if needed. All data sets were simulated using a statistical software. You can also find Excel temples in the attachment with my announcement, which helps you a lot! Part A. A researcher intended to investigate the potential difference in BMI between men and women. He also tried to evaluate the effectiveness of...
