Suppose we want to create a method for the class BinaryTree that counts the number of times an object occurs in the tree. The header of the method could be as follows: public int count(T anObject) a. Write this method using a private recursive method of the same name. b. Write the method using one of the iterators of the binary tree. c. Compare the efficiencies of the previous two versions of the method.

STA3032 MODULE 1 ARTICLE I. 1.1-1.3.5 1) 1.1 Descriptive Statistics a) Population parameters- “a numerical summary concerning the complete collection of subjects” i) Notated by Greek characters b) Sample statistics- “a numerical summary concerning a subset of the population, from which we try to draw inference about the population parameter” i) Notated by the hat symbol over a population parameter c) i.e. σσstandard deviation 2) 1.2 Summary Statistics 3) 1.2.1 Location a) Mode: most frequent number b) Mean: average of the observations c) p percentile: p% of data are less than that specific value and 100%-p% are greater i) position of p percentile value: (p/100)(n+1) (1) i.e. value x was in the 90 percentile which
