WRITTEN WORK (MELC 3); Dependent t-test Direction: Study the table below. Answer the questions that follow. Problem: A new fitness program is devised for obese people. Each participant's weight was measured before and after the program. Weight Before 147 127 121 131 131 120 133 127 124 143 After 143 122 118 128 126 119 130 124 124 143 Question Answer 1. What is the independent variable 2. What is the dependent variable? 3. Is the data categorical measured? 4. What inferential statistics application is used? 5. State the Statistical Hypothesis 6. Determine the test statistics 7. What is the degree of freedom? .Please refer to page 7 (Module 3: Hypothesis Testing) on how to answer this activity. Print and glue the excel result. Interpret it by stating whether to ACCEPT or REJECT the null hypothesis.SAMPLE PROBLEM Independent t-test Problem: The following experiment was run to determine whether or not different flavors of ice buko melt at different speeds. Two flavors two flavors (X and Y] of ice buko were stored in the same freezer in similar-sized containers. For each observation, one teaspoonful of ice buko taken from the freezer, transferred to a plate, and the melting time at room temperature was observed to te nearest second. Nine observations were taken on each flavor. These are shown in the following table, and the normal probability plots of these data are shown below. Flavor Melting Time X 1009 987 955 1074 994 1040 1037 999 1013 820 970 980 872 975 861 963 857 977 Determine whether or not different flavors of ice buko melt at different speeds. Question Answer 1. What is the independent The type of flavor variable 1. What is the dependent The melting time variable? 3.Is the data categorical or measured measured? 2. What inferential statistics Two dependent Samples( mean of x application is used? and y) 4. State the statistical Hypothesis Is there a significant difference on the melting time of flavor x and y of ice buko? 5. Determine the test statistics Independent T-test 6. What is the degrees of freedom? 9-1 = 8
