Question

e None of Ouestions 10 through 30 25 20 13 cinclusive) refers to the frequeney plot below based on at total of 15 10 10 In the above chart, what is the mode of the data set? 3.5 b 25.0 e 7.0 d 5.0 e None of the above How can one describe the shape of the distribution (based on the envelope). a Negative skewed b Positive skewed d Negative variance e None of the above are true. Based on the chart, what is the probability that a zero does NOT result from a single independent trial. 296 98% None of the above Cannot be determined with the information given. Based on the chart, what is the probability of a'5 or *6 occurring with a single independent trial? 5% 5% 5% not be determined with the information given.

Explanation / Answer

10

d)5.0

The observation with highest frequency

11)

a)negatively skewed

because the left tail is longer than right tail

12)

P(zero does not result) = 1-P(zero results) 1-0.02=0.98 =98%

b)98%

13)

P(5 or 6 occuring) =P(5 occuring)+p(6 occuring) = [25/100 +20/100]*100 = 45%
