The Volcanic Explosivity Index (VEI) is based primarily on the amount of material ejected from a volcano, although other factors play a role as well, such as height of plume in the atmosphere. The following table shows the number of volcanic eruptions (N) over the past 10,000 years having a VEI of between 2 and 7.
There are also VEI values of 0, 1, and 8. There is a level 0 volcano erupting somewhere on the Earth essentially all the time. There are one or more level 1 volcanoes essentially every day. The last known level 8 volcano was about 26 000 years ago
- a. Show the resulting data trendline, with equation and R2 value, on the appropriate graph type (xy scatter, semilog, or log–log) to make the data appear linear
- b. How many level 1 volcanoes does the model predict should have occurred in the last 10,000 years?
- c. How many level 8 volcanoes does the model predict should have occurred in the last 10,000 years?

There are five parameters that must be considered: temperature, quenching rate, cooling time, carbon content, CO₂ concentration. It is desired to determine which of these parameters has the most influence on the process. There are two levels for each parameter as shown below. Temperature (°C) Quenching Rate(°C/s) Cooling time (s) Carbon Content (wt% C) CO₂ Concentration (%) Eight experiments were defined as follows: Experiment Carbon Content (wt% C) 1 2 3 4 5 6 7 8 1) What size orthogonal array should be used for evaluation (assume noise is negligible)? 2) Generate the array with the level values (i.e. Level 1 and Level 2). 1 1 1 1 6 6 6 6 Quenching Rate (°C/s) 35 35 140 140 35 35 140 140 Four trials were run for the experiments defined above: Experiment 1 2 3 4 5 6 7 8 Level 1 760 35 1 1 5 T1 68.00 69.84 74.36 71.71 91.27 54.39 64.65 60.31 Cooling Time 1 1 300 300 300 300 1 1 T2 61.41 64.76 61.30 58.42 90.89 Level 2 900…arrow_forwardIn measuring the surface tension of a liquid (drop weight method), 20 drops of the liquid (r = 0.2cm) falling apart from the tip whose diameter is 0.4 cm were found to weight 0.95 gram.
