1)Use inductive reasoning to conjecture the rule selected to the final answer. Try to prove your reasoning.

Select a number:

Multiply by 6:

Subtract 18 from the answer:

Divide by 6:

Subtract the original number:

2) For your problem number draw a Venn diagram and then answer the three questions.

In a survey of 18 college students, it was found that 9 were taking an English class, 13 were taking a math class, and 7 were taking both English and math. How many students were taking a math class only? How many students were taking an English class only? How many students were taking neither.

3) Provided below are the sizes of 15 farms, in acres, randomly selected from the 12) state of Oregon. The mean of this sample is 451 acres.

2560 258 373 250 285 399 268 211

89 232 408 388 214 373 457

a. Find the median of the sample and compare it to the mean and discuss the difference.

b. Find the mean and the median if you throw out the 2560 acre farm which has the largest area by far. What does this tell you?
