Suppose that the country has had the following inflation rates over the past 14 years: 6.0; 6.7; 10.4; 11.9; 7.2;3.5; 8.4; 7.5; 2.8; 4.3; 1.9; 3.9; 0.9; 0.7. Use the χ² goodness-of-fit test to determine whether the random variable ξ corresponding to this inflation rate is normally distributed or not. Consider 6 intervals of equal length. Determine the value of the test statistic and the critical range.
