The true percentage of left-handed people is 13% (p = .13)

  1. a. If we survey two hundred people, how many left handers do you expect to survey?

b. If you repeat this survey, will you always get this number of left-handers (the expectation)? Why or why not?

c. What is the spread (standard deviation) of the sample proportions?

d. Use the empirical rule to describe where we expect sample proportions to lie if we repeated this survey (with size of 200 people) over and over again

68% of sample proportions would lie between ______________and _____________

95% of sample proportions would lie between _____________and______________

99.7% of sample proportions would lie between _____________and______________

Approximately 13% of the population are left-handed. If three people are randomly selected, what is the probability that all are left- handed?   (round to 4 decimal places) If three people are randomly selected, what is the probability that at least 1 person is not left handed?   (round to 4 decimal places) Notice that these two events are complementary (the probabilities do add up to 1).
