Dice are different (ExH). In Mindscape 14 you probably used ideas similar to those in the analogous text example on coin tosses. Yet how are the two experi ments different? What qualities might you look for (or look for the absence of) in a sequence of alleged random die tosses that would not apply in the case of coin tosses? In particular, can you tell which of the sequences below was generated by rolling an actual die and which was created by a person writing down what they think of as random digits (before reading this text)?

I am interested in process. You may use a computer for integration, finding determinants and doing Kramer's.arrow_forwardWhy the correct answer is letter A? Students in an online course are each randomly assigned to receive either standard practice exercises or adaptivepractice exercises. For the adaptive practice exercises, the next question asked is determined by whether the studentgot the previous question correct. The teacher of the course wants to determine whether there is a differencebetween the two practice exercise types by comparing the proportion of students who pass the course from eachgroup. The teacher plans to test the null hypothesis that versus the alternative hypothesis , whererepresents the proportion of students who would pass the course using standard practice exercises andrepresents the proportion of students who would pass the course using adaptive practice exercises.The teacher knows that the percent confidence interval for the difference in proportion of students passing thecourse for the two practice exercise types (standard minus adaptive) is and the percent…arrow_forward3. A spring is stretched 6 in. by a mass that weighs 8 lb. The mass is attached to a dashpot mechanism that has a damping constant of 0.25 lb-sec./ft. and is acted on by an external force of 4 cos 2t lb. a.
