Week3 assignment

Find or create a set of data that has a normal distribution. The data set should include at least 50 values and include its source. Once you have the data collected, present it in the following ways:

• A relative frequency table using the classes of your choice.
• A relative frequency histogram using same classes as the relative frequency table.

Calculate the following values for your data set:

• The mean
• The standard deviation
• Sketch the normal curve on the same axes as the relative frequency histogram.

Once you have established the mean and standard deviation of the distribution, create another set of 100 normally distributed values using these values. The easiest way to do this is to use the random normal function on the calculator:
