Question
EXAMPLE Formulating Hypothesis Statements 1. Do female students' study, on average, more than male students do? Null Hypothesis (H): On average, women do not study more than men do. Alternative Hypothesis (H,): On average, women do study more than men do. 2. Are Side Effects Experienced by Fewer than 205 of 3. The average TV viewing time of all five – year old children in the province is more than 4 hours daily. Patients? Pharmaceutical company wants to claim that the proportion of patients who experience side effects is less Null Hypothesis (H,): The average viewing time of all five- year old children in the province is equal to 4 hours daily. than 20%. (The claim that the company hopes to prove is used as the alternative hypothesis.) In Symbol: Hp: µ = 4 Null Hypothesis (H,): 20% (or more) of users will experience side effects. Alternative Hypothesis (H.): The average viewing time In Symbol: Ho: p 20%; Alternative Hypothesis (H.): Fewer than 20% of of all five- year old children in the province is more than 4 hours daily. users will experience side effects. In Symbol: H.: µ > 4 In Symbol: H.: p< 20% Note: We use p since the parameter is proportion. Note: We use u since the parameter is average.
