What is the RPI index? How can the defective product rate of a production process be determined by using the RPI index? The average distribution range of 2 samples consisting of 4 units is R = 10.8 mm. The tolerance limit is plus – minus 10 mm. Calculate the RPI and evaluate if it will reject. What happens to the reject situation if the tolerance limit is plus-minus 20 mm?
A researcher read that firearm-related deaths for people aged 1 to 18 were distributed as follows: 74% were accidental, 16% were homicides, and 10% were suicides. In her district, there were 68 accidental deaths, 27 homicides, and 5 suicides during the past year. At alpha=0.10, test the claim that the percentages are equal. 1. Determine the critical region. 2. What is the critical value. 3. What is your decision? 4. What is your conclusion? 5. State the hypotheses and identify the claim: 6. What is the test value.(Leave answer in 3 decimal places)

The authors of the paper "Dynamics of Canopy Structure and Light Interception in Pinus elliottii, North Florida" (Ecological Monographs (1991):33-51) planned an experiment to determine the effect of fertilizer on a measure of leaf area. A number of plots were available for the study, and half were selected at random to be fertilized. In order to assure that the plots to receive the fertilizer and the control plots were similar, prior to beginning the experiment tree density (the number of trees per hectare) was recorded for six plots to be fertilized and six control plots, resulting in the given data. Do the plots differ in tree number? Do you have any concerns about their experimental design? Fertilizer plots 1320 1216 1312 1280 1216 1312 control plots 1104 1072 1088 1150 1272 1280
Suppose a researcher is interested in the relationship between periodontal disease and a number of negative health outcomes. One outcome of particular interest to the researcher is hypertension (assume defined as systolic blood pressure above 140 mmHG). Suppose a team gathers a SRS of 348 participants with periodontal disease, and finds the sample average systolic blood pressure to be 157 mmHG. A) Using an assumed σ=16 mmHG, conduct a 1 sample Z test to determine if there is a relationship between periodontal disease and hypertension in this population. (Use α=0.05)
