Question 4 of 40

0.0/ 2.5 Points

Joe dealt 20 cards from a standard 52-card deck, and the number of red cards exceeded the number of black cards by 8. He reshuffled the cards and dealt 30 cards. This time, the number of red cards exceeded the number of black cards by 10. Determine which deal is closer to the 50/50 ratio of red/black expected of fairly dealt hands from a fair deck and why.

 

 

A. The first series is closer because 1/10 is farther from 1/2 than is 1/8.

  

 

B. The series closer to the theoretical 50/50 cannot be determined unless the number of red and black cards for each deal is given.

  

 

C. The second series is closer because 20/30 is closer to 1/2 than is 14/20.

  

 

D. The first series is closer because the difference between red and black is smaller than the difference in the second series.

A study of 600 college students taking Statistics 101 revealed that 54 students received the grade of A. Typically 10% of the class gets an A. The difference between this group of students and the expected value is not significant at the 0.05 level. What does this mean in this case?

 

 

A. The probability that the difference occurred due to chance is less than 0.05.

  

 

B. The probability of getting an A is 10% and only 9% got an A in this study. The difference is less than 5% so it is not significant.

  

 

C. There is not enough information to make any conclusion.

  

 

D. The probability that the difference occurred due to chance is more than 0.05.

Jody checked the temperature 12 times on Monday, and the last digit of the temperature was odd six times more than it was even. On Tuesday, she checked it 18 times and the last digit was odd eight times more than it was even. Determine which series is closer to the 50/50 ratio of odd/even expected of such a series of temperature checks.

 

 

A. The Monday series is closer because 1/6 is closer to 1/2 than is 1/8.

  

 

B. The Monday series is closer because 6/12 is closer to 0.5 than is 8/18.

  

 

C. The Tuesday series is closer because the 13/18 is closer to 0.5 than is 9/12.

  

 

D. The series closest to the theoretical 50/50 cannot be determined without knowing the number of odds and evens in each series.
