Calculation: We used the chi-square distribution to test the hypotheses. Assuming that, it is normal population distribution.
The population standard deviation, , with sample size, .
The sample standard deviation s of x, can be calculated by using Excel as follows:
Step 1: Enter data of x1 in cell A1 to A10.
Step 2: Use command STDEV(A1:A10).
Therefore, the obtained sample standard deviation
The chi-square test statistic is calculating as:
Degrees of fredom for
Conclusion:Assume the normal population distribution. statistic 10.78 with 9 degrees of freedom.
