Creating a Normal Model with Death Rates by Year

[Shay10825]

Hi everyone! I need some help. I have to make a normal model from the following data:

Year...Deaths Country
...or area/,per 1,000
...population

2005 , 8.25
2006 , 8.26
2007 , 8.26
2008 , 8.27
2009 , 8.28
2010 , 8.29
2011 , 8.29
2012 , 8.30
2013 , 8.31
2014 , 8.32
2015 , 8.34
2016 , 8.35
2017 , 8.37
2018 , 8.39
2019 , 8.42
2020 , 8.45
2021 , 8.49
2022 , 8.54
2023 , 8.58
2024 , 8.63
2025 , 8.68
2026 , 8.74
2027 , 8.79
2028 , 8.85
2029 , 8.91
2030 , 8.97
2031 , 9.03
2032 , 9.09
2033 , 9.15
2034 , 9.21
2035 , 9.27
2036 , 9.32
2037 , 9.37
2038 , 9.42
2039 , 9.46
2040 , 9.50
2041 , 9.53
2042 , 9.56
2043 , 9.58
2044 , 9.59
2045 , 9.60
2046 , 9.60
2047 , 9.60
2048 , 9.59
2049 , 9.57
2050 , 9.55

When I make a histogram do I plot the year on the x-axis and the deaths on the y-axis. When I'm making the normal model what is the x-axis (what do I find the std dev of? The year or the death rate?) Would I put the deaths on the x-axis for the normal model (bell curve)?

Any help would be appreciated! Thank you.Yes, you should plot the year on the x-axis and the death rate (per 1,000 population) on the y-axis for the histogram. For the normal model, the x-axis should be the death rate (per 1,000 population), which is what you would find the standard deviation of. The death rate would be plotted on the x-axis for the normal model (bell curve).

Hi there,

To create a normal model with this data, you would first need to determine the mean and standard deviation of the death rates. The mean can be calculated by taking the average of all the death rates, and the standard deviation can be calculated using a statistical software or spreadsheet program.

Once you have the mean and standard deviation, you can plot the data on a histogram with the death rates on the x-axis and the frequency on the y-axis. The histogram will give you an idea of the distribution of the data and whether it follows a normal distribution.

To create the normal model, you would use the mean and standard deviation to plot a bell curve. The x-axis of the normal model would represent the death rates, and the y-axis would represent the probability of each death rate occurring. The standard deviation would determine the spread of the curve, with the mean being the highest point.

I hope this helps! Good luck with your project.
