Class Exercise 28 Dengue Cases A local doctor is demanding immediate assistance claiming that the rate of new dengue cases in a certain barangay is higher than the current World Health Organization's rate of 56%. Upon arrival, you found that there were indeed 113 cases of dengue among 190 members of the small village. Is the local doctor correct in his assessment at a 0.01? A. Given B. Problem C. Hypothesis D. Formula and Test Statistic E. Decision Basis Traditional Method p-value Method F. Statistical Traditional Method p-value method Decision G. Contextual Decisionthe 2010 2 Qualitative Data: Testing for Proportions or Frequencies Learning outcomes: 1. Examine the statistical technique for qualitative data 2. Identify the sample proportions for parametric data 3. describe and compare the equal and unequal frequencies for the chi-square Qualitative Data: Testing for Proportions or Frequencies Remember that there are two kinds of data; scores and frequencies. The previous discussion on hypothesis testing all involved observations that were measured quantitatively and we treated the data using its mean. This time, we focus our discussion on testing hypothesis when frequencies (we just count the number of observations) or proportions (percentages) are concerned. B.2.2.1 Testing a Claim About a Proportion Sometimes our hypothesis involves making a statement about the population or simply validating a statistic presented by other people. The following shows how we can test such proposition with a sample. tration: The 2010 FIES (Family Income Expenditure Survey) claims that 30% of Filipino Families live below the poverty line. You want to see if the data has changed since then. Thus, you surveyed 500 families and found that 25% of the families now live below the poverty line. Is this change significantly different from the FIES findings at a=0.05? A. Given P = 30% n=500 sample proportion(p)= 25% B. Problem = Population proportion vs. sample proportion C. Hypothesis Ho: p = 30% Ha: p # 30% D. Formula and Test Statistic 0.25 - 0.30 = -2.43 2 = P_ Vpqzthe 2010 2 A. Given P = 30% n=500 sample proportion(p)= 25% B. Problem Population proportion vs. sample proportion C. Hypothesis Ho: p = 30% Ha: p # 30% D. Formula and Test Statistic 0.25 - 0.30 2= P_ Vpqz =-2.43 (0.300.70/500 E. Decision Basis traditional method p-value method Two-tailed Test z= -2.43 has an area of 0.0075 z = 1 1.96 ; 95% two-tailed test thus p-value is multiplied by 2 therefore 0.015 F.
