In a sample of 200 customers, 110 applied for the Silver, 55 for Gold, and 35 for Platinum. Is there evidence to suggest that the percentages for this promotion may be different from the historical proportions? What is the expected number of customers applying for the SILVER card in this sample if the historical proportions are true? What is the expected number of customers applying for the GOLD card in this sample if the historical proportions are true? What is the expected number of customers applying for the PLATINUM card in this sample if the historical proportions are true? What is the value of the degrees of freedom? df = _____ What is the chi-square statistic? ( 2 decimal places) What is the p-value? ( 3 decimal places) Reject the null hypothesis or Fail to reject the null hypothesis.
