Statistics Probabilities



Statistics Probabilities Questions with Work



1.      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?

For starters: 
I went here and found this which I am sharing because I feel others may want to use this in the future:


However, I went to SU tutors and received help. I screen shot everything this time. I am now going to protect myself from tutors that make mistakes and lie about it. This time, I had a tutor that in fact made a mistake and corrected it, and even explained everything thoroughly. 

Here is what I learned from Asmita:

n=15 x=5 p=0.5 (1/2) and for the final answer: .092

2.      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, why or why not? No, I do not ‘think’ this graph that I cannot include in this question is a probability distribution. Why? Because this is not a flip of a coin experiment. However, my first question, ‘is’ a probability experiment, I’m just sayin…
