WebAt the 1% level of significance, the evidence is insufficient to conclude that the average daily January temperature does not follow a normal distribution. (b) Find the value of the chi-square statistic for the sample. (Round the expected frequencies to at least three decimal places. Round the test statistic to three decimal places.) WebChi-Square Test Chi-Sq = 8.647 DF = 4, P-Value = 0.071 Note that there are 3 cells with expected counts less than 5.0. In the above example, we don't have a significant result at a 5% significance level since the p-value (0.071) is greater than 0.05.
