An employee claims that 20% of the email she receives is personal, 60% is work related, and 20% is spam. The high level of spam she is receiving is frustrating, so she creates some new filters. She then selects a random sample of 50 emails over the next several weeks. She determines that she received 10 personal emails, 38 work related emails, and 2 spam emails. She would like to know if the distribution of emails she receives has changed What is the value of the chi-square test statistic and P-value? Find the chi-square table here. O x2 = 8.53, P-value is between 0.01 and 0.02 %3D O x2 = 8.53, P-value is between 0.025 and 0.05 O x? = 33.68, P-value is less than 0.0005 %3D O x2 = 33.68, P-value is greater than 0.25 %3D
