Use "chi-square test" to test the hypothesis that the data given above follows an exponential
distribution. Let the level of significance \alpha =0.05. Some of the Chi-Square critical values:
\chi _(0.05,3)^(2)=7.82,\chi _(0.05,2)^(2)=5.99,\chi _(0.05,1)^(2)=3.84.
Note that the probability density function and the cumulative distribution function of an
exponentially distributed random variable x with the parameter \lambda are given as follows:
