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…
