Mariam is interested in testing whether ZU students spend, on average, more than 30 minutes on WhatsApp chatting per day. She tested the hypothesis Ho:pS 30 versus Hp> 30. The null hypothesis is not rejected. State the appropriate conclusion. The mean time spent on WhatsApp chatting daily by ZU students is less than 30 minutes. There is no sufficient evidence that ZU students spend more than 30 minutes on WhatsApp chatting daily. The mean time spent on WhatsApp chatting daily by ZU students is at least 30 minutes. O There is no sufficient evidence that ZU students spend at most 30 minutes on WhatsApp chatting daily. OO0 0

QUESTION 20 Mariam is interested in testing whether ZU students spend, on average, more than 30 minutes on WhatsApp chatting per day. She tested the hypothesis Ho: ps 30 versus H:> 30. The null hypothesis is not rejected. State the appropriate conclusion. O The mean time spent on WhatsApp chatting daily by ZU students is less than 30 minutes. O There is no sufficient evidence that ZU students spend more than 30 minutes on WhatsApp chatting daily. O The mean time spent on WhatsApp chatting daily by ZU students is at least 30 minutes. O There is no sufficient evidence that ZU students spend at most 30 minutes on WhatsApp chatting daily. QUESTION 21 Classify each of the following statements about the p-value as either true or false: B A p-value indicates the strength of the evidence against the null A. True hypothesis. B. False 8 The larger the p-value is, the more conclusive the evidence is against the null hypothesis. 8 Finding the p-value does not require the knowledge of a. B Ap-value tells us the probability that the null hypothesis is true. A p-value of a two-tailed test may exceed 1.
