Transcribed Image Text:B. Find the Expected Frequencies (E) based on the franchisor's reported relative frequencies.
This table shows the relative frequencies presented to Maria by the franchisor along with the distribution
of her monthly hot tub sales for 2021. Find the Expected Frequencies. Note: Round off the Expected
frequencies to two digits passed the decimal point (x.00). The total for the Expected Frequencies
should equal the total of the Observed Frequencies. WARNING: If your Expected Frequencies are
wrong, the value of your Chi-Square test statistic, the p-value, and effect size will be wrong.

# 4: Compose the Decision Rule: Model your answer on the examples shown in Clear-Sighted Statistics.
Your decision rule must be based on the critical value of Chi-Square and NOT the p-value. Failure
to do so will results in a major grading penalty.
