{Example 9
Calculate and record the observed frequencies of sample means in each of the classes indicated in the following table. Note that interval endpoints are midpoint 0.5*width and the interval midpoint is average of two endpoints. Use 9.31, 9.61, 9.91, 10.21, 10.51 and 10.81 as the bin boundaries for the Excel HISTOGRAM procedure.

3. What was the observed frequency of sample means that fell between 9.91 and 10.21?
{Example 2}
Enter the seven expected frequencies into a column of the Excel worksheet and the seven observed frequencies into another column. Make sure that expected and observed frequencies for the same class are entered in the same row. Check that both columns of data sum to 100 (within rounding error). If they do not, correct your error(s). {Example3} 04:14 PM Market Brief ENG 21-06-2023 9
