Question 1
The lifetimes (in units of 106 seconds) of certain satellite components
are shown in the frequency distribution given in 'Datasetl'.
1. Draw a frequency polygon, histogram and cumulative frequency
polygon for the data.
2. Calculate the frequency mean, the frequency standard deviation,
the median and the first and third quartiles for this grouped data.
3. Compare the median and the mean and state what this indicates
about the distribution. Comment on how the answer to this ques-
tion relates to your frequency polygon and histogram.
4. Explain the logic behind the equations for the mean and standard
deviation for grouped data, starting from the original equations
for a simple list of data values.
5. Set up the structure for a statistical test to determine whether the
data is normally distributed with the given mean and standard
