TH 160-Statistics I Course Review Questions Monroe Community College 2, Based on the boxplot below, answer the following questions: Morning grooming times S 40 If we were going to create a histogram, would the histogram be skewed to the left, skewed to the right, or a normal distribution? Approximate the range and the 5-number summary. a. b. for Chapters 5 and 6 the number of chicken wings a patron at Duff's might 3. The following probability distribution reflects consume on a Friday night. Ptxl 0.1 0.25 0.3 0.2 0.1 0.05 5 a. b. What is the probability that a patron will consume at least 1 chicken wing this Friday? What is the probability that a patron will consume at most 3 chicken wings this Friday?Explanation / Answer
Solution2a:
from box plot it is not normal since the center line which is median is not in the moddle of box.
IT IS SKEWED RIGHT
range=max-min=60-5=55
FIVE NUM SUMMARY IS
min=5
Q1=12
Q2=18
Q3=32
max=60
Solution2:
P(atleast1)
P(X>=1)=P(X=1)+P(X=2)+P(x=3)+P(X=4)+P(X=5)
=0.25+0.3+0.2+0.1+0.05
=0.9
Solutionb:
P(atmost 3)=P(x<=3)
P(X=0)+P(X=1)+P(X=2)+P(X=3)
=0.1+0.25+0.3+0.2
=0.85
ANSWER:0.85
