The horizontal axis represents three groups: A, B, and C. The vertical axis represents measurements from 0.0 to 10.0 with an interval of 2.5. The approximate data from graph are as follows: For group A, majority of measurements lie between 1 to 5 with widest bulge at 2 point 7. For group B, majority of measurements lie between 1 and 6 with the widest bulge at 2 point 5. For group C, majority of measurements lie between 2 point 5 and 7 with the widest bulge at 6 point 5. A) In which of the groups is the frequency distribution of measurements approximately symmetric? B) Which of the frequency distributions show negative skew? C) Which of the frequency distributions show positive skew?
- Determine whether the following statements are true or false? (a) When interpolating n data points, (x;, y), i = 1,2,..., n, using polynomial interpolation, there are n unknown coefficients to determine. (b) When interpolating n data points, (x;, yi), i = 1,2, ., n, using cubic spline interpolation (not-a-knot spline), there are 4(n - 2) unknown coefficients to determine. (c) When performing linear curve fitting for n data points, (x;, yp), i = 1,2,..., n, there are 2n unknown model parameters to determine. (d) When performing nonlinear curve fitting for n data points, (x;, Vi), i = 1,2. unknown model parameters depend on the model form assumed.A small university town has four local food restaurants that make deliveries. A group of marketing students were assigned to do a research project for their class assignment to compare how promptly the four restaurants deliver. On randomly chosen days, they order a chicken rice set from each restaurant, then record the elapsed time until the chicken rice set delivered to their college. Assume that their college is approximately the same distance from the four restaurants. The data are analysed using SPSS and the results are illustrated in Table 2a and 2b. question: Complete the ANOVA table (Table 2b) and calculate theF-ratio.A small university town has four local food restaurants that make deliveries.

The article “The Epiphytic Lichen Hypogymnia physodes as a Biomonitor of Atmospheric Nitrogen and Sulphur Deposition in Norway” (Environ. Monitoring Assessment, 1993: 27–47) gives the following data (read from a graph) on x ¼ NO3 wet deposition (g N/m2 ) and y ¼ lichen N (% dry weight): (refer to chart) The author used simple linear regression to analyze the data. Use the accompanying MINITAB output to answer the following questions: a. What are the least squares estimates of b0 and b1? b. Predict lichen N for an NO3 deposition value of .5. c. What is the estimate of s? d. What is the value of total variation, and how much of it can be explained by the model relationship?How long does it take for the surfer to go from a trough tothe next trough (min)?
