Question 1 of 40Jody checked the temperature 12 times on Monday, and the last digit of the temperature was odd six times more than it waseven. On Tuesday, she checked it 18 times and the last digit was odd eight times more than it was even. Determine which seriesis 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 eachseries.Question 2 of 40If you flip a coin three times, the possible outcomes are HHH, HHT, HTH, HTT, THH, THT, TTH, TTT. What is the probability thatat least two heads occur consecutively?A. 1/8B. 3/8C. 5/8D. 6/8Question 5 of 40A study of 600 college students taking Statistics 101 revealed that 54 students received the grade of A. Typically 10% of theclass gets an A. The difference between this group of students and the expected value is not significant at the 0.05 level. Whatdoes 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.Question 6 of 40If a person is randomly selected, find the probability that his or her birthday is not in May. Ignore leap years. There are 365 daysin a year. Express your answer as a fraction.A. 335/365B. 334/365C. 336/365D. 30/365Question 8 of 40Suppose you pay $1.00 to roll a fair die with the understanding that you will get back $3.00 for rolling a 5 or a 2, nothingotherwise. What is your expected value?A. $1.00B. $0.00C. $3.00D. −$1.00Question 10 of 40A study of students taking Statistics 101 was done. Four hundred students who studied for more than 10 hours averaged a B.Two hundred students who studied for less than 10 hours averaged a C. This difference was significant at the 0.01 level. Whatdoes this mean?A. The probability that the difference was due tochance alone is greater than 0.01.B. There is less than a 0.01 chance that the firstgroup’s grades were better by chance alone.C. The improvement was due to the fact that morepeople studied.D. There is not enough information to make anyconclusion.Question 11 of 40Suppose you have an extremely unfair die: The probability of a 6 is 3/8, and the probability of each other number is 1/8. If youtoss the die 32 times, how many twos do you expect to see?A. 2B. 4C. 3D. 5Question 12 of 40A class consists of 50 women and 82 men. If a student is randomly selected, what is the probability that the student is awoman?A. 32/132B. 25/66C. 50/132D. 82/132Question 13 of 40If you flip a coin three times, the possible outcomes are HHH, HHT, HTH, HTT, THH, THT, TTH, TTT. What isthe probability of getting at most one head?A. 4/9B. 5/6C. 7/8D. 5/8Question 14 of 40In the first series of rolls of a die, the number of odd numbers exceeded the number of even numbers by 5. Inthe second series of rolls of the same die, the number of odd numbers exceeded the number of even numbersby 11. Determine which series is closer to the 50/50 ratio of odd/even expected of a fairly rolled die.A. The second series is closer because the difference between odd and even numbers is greater than the difference for thefirst series.B. The first series is closer because the difference between odd and even numbers is less than the difference for the secondseries.C. Since 1/2 > 1/5 > 1/11, the first series is closer.D. The series closer to the theoretical 50/50 cannot be determined unless the total number of rolls for both series is given.Question 15 of 40A die with 12 sides is rolled. What is the probability of rolling a number less than 11? Is this the same as rolling atotal less than 11 with two six-sided dice? Explain.A. 2/6B. 3/6C. 4/6D. 5/6Question 17 of 40Suppose you buy 1 ticket for $1 out of a lottery of 1000 tickets where the prize for the one winning ticket is to be$500. What is your expected value?A. $0.00B. −$0.40C. −$1.00D. −$0.50Question 18 of 40Suppose you have an extremely unfair coin: the probability of a head is 1/3 and the probability of a tail is 2/3. Ifyou toss the coin 72 times, how many heads do you expect to see?A. 12B. 22C. 24D. 26Question 19 of 40The data set represents the income levels of the members of a country club. Estimate the probability that arandomly selected member earns at least $98,000.112,000 126,000 90,000 133,000 94,000 112,000 98,000 82,000 147,000 182,000 86,000 105,000140,000 94,000 126,000 119,000 98,000 154,000 78,000 119,000A. 0.4B. 0.6C. 0.66D. 0.7Question 20 of 40Suppose you have an extremely unfair coin: the probability of a head is 1/5, and the probability of a tail is 4/5. Ifyou toss the coin 40 times, how many heads do you expect to see?A. 8B. 6C. 5D. 4
