Statistics and Probability Distribution
Please show all of the steps and processes you used to solve each of the problems
1. Would you suspect that the IDEA surveys sent to South students each term could be biased in the responses received? Why or why not?
2.Using the data set below, please calculate the:
12 16 12 10 20 10 10
- Mean =
- Median =
- Mode =
3. Suppose we want to determine the (binomial) probability (p) of getting 5 heads in 15 flips of a 2-sided coin. Using the Binomial table in the appendix of the text, what values of n, x, and p would we use to look up this probability, and what would be the probability?
4. Learning is a lifetime activity. For some, it means learning from everyday experiences; for others, it means taking classes in a more traditional atmosphere. The percentage of people participating in organized learning situations during 2002 for each age group is reported here by NIACE.
Is this a probability distribution? Explain why or why not.

Is the volume of pottassium hydroxide more, less or the same
: Compare the amount of .200 moles of KOH needed to neutralize 50 mL of .200 moles of HNO3 with the amount of .200 moles of KOH needed to neutralize 50 mL of .200 moles of CH3COOH. Is the volume of KOH more, less or the same.
