Simulations Assignment

At a large university, 15% of students are left-handed. A psychology professor selects a random sample of 10 students and records L = the number of left-handed students in the sample. What kind of result could be recorded for each trial?

0, 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 left-handed students

Josh likes to play an outdoor beanbag toss game in his spare time. On any toss, he has about a 30% chance of getting a bag into the hole. As a challenge one day, he decides to keep tossing beanbags until he makes it. What kind of result could be recorded for each trial?

1, 2, 3, 4, 5, 6, 7, . . . attempts

At a large university, 15% of students are left-handed. A psychology professor selects a random sample of 10 students and records L = the number of left-handed students in the sample. Starting on line 1 of the random-number table, how many left-handed students occur in the first trial of the simulation if we let 00-14 represent left-handed students?

Josh likes to play an outdoor beanbag toss game in his spare time. On any toss, he has about a 30% chance of getting a bag into the hole. As a challenge one day, he decides to keep tossing beanbags until he makes it. Starting on line 5 of the random number table, how many times does Josh have to toss the beanbag in order to make it in the hole if we let success = 0-2 and failure = 3-9?

At a large university, 15% of students are left-handed. A psychology professor selects a random sample of 10 students and records L = the number of left-handed students in the sample. Let 00-14 represent selecting a left-handed student. Starting on line 2 of the random-number table, complete 4 trials of the simulation, and then enter the proportion (as a decimal) of these trials for which you obtained the number of successes shown in the table.

A = 0.25 B = 0.25 C = 0.25 D = 0.25

At a large university, 15% of students are left-handed. A psychology professor selects a random sample of 10 students and records L = the number of left-handed students in the sample. Describe the assignment of digits to the outcomes being left-handed and being right-handed:

left-handed = 00-14, right-handed = 15-99

Josh likes to play an outdoor beanbag toss game in his spare time. On any toss, he has about a 30% chance of getting a bag into the hole. As a challenge one day, he decides to keep tossing beanbags until he makes it. Describe the randomization process: We will read across the random-number table, ______at a time, to represent the _____________ until Josh makes ____.

one digit; number of tosses; 1

Josh likes to play an outdoor beanbag toss game in his spare time. On any toss, he has about a 30% chance of getting a bag into the hole. As a challenge one day, he decides to keep tossing beanbags until he makes it. Describe the assignments of digits to whether or not Josh gets the bag in the hole:

success = 0-2, failure = 3-9

We will read across the random number table, X one digit _______ at a time, to represent the handedness of ____ randomly selected students.

two digits; 10
