If A is the number of people in the sample who preferred Product A, using your data, what is xA bar and sA (Product A: 13, Product B: 4, Product C: 13)
Homework Answers
Solution:
n=A+B+C=13+4+13=30
X bar=sample proportion=x/n=13/30=0.4333333
sA =sample standard deviation=sqrt(p^*(1-p^)/n
=sqrt(0.4333333*(1-0.4333333)/30)
= 0.09047201

We will be using Excel to simulate the number of left-handed people in a particular sample. Left-handed people make up about 10% of the population. We will randomly pick numbers between 1 and 10, where 1 represents a left-handed person and 2 - 10 represents a right-handed person. This should result in about 10% of our sample being left-handed. Please note there are five parts to this question. 1. Create a pie graph in Excel to show the proportion of...
