Suppose we want to determine the (binomial) probability(p) of getting 4 heads in 15 flips of a 2-sided coin. Using the Binomial Probabilities Table in Appendix B 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 the table that follows, answer the following questions:
Would the correlation between x and y in the table above be positive or negative?
Find the missing value of y in the table.
How would the values of this table be interpreted in terms of linear regression?
If a "line of best fit" is placed among these points plotted on a coordinate system, would the slope of this line be positive or negative?
