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 would like to know if the distribution of emails she receives has changed. What are the appropriate hypotheses? O Ho: The distribution of emails received is no longer 20% personal, 60% work related, and 20% spam. Ha: The distribution of emails received is still 20% personal, 60% work related, and 20% spam. O Họ: The distribution of emails received is still 20% personal, 60% work related, and 20% spam. Hạ: The distribution of emails received is no longer 20% personal, 60% work related, and 20% spam. O Ho: The distribution of emails received is still 20% personal, 60% work related, and 20% spam. Hạ: She now receives less than 20% spam. O Ho: The distribution of emails received is still 20% personal, 60% work related, and 20% spam. Hạ: She now receives an amount different from 20% spam.
