Joey is interested in investigating so-called hot streaks in foul shooting among basketball players. He’s a fan of Carla, who has been making approximately 80% of her free throws. Specifically Joey wants to use simulation methods to determine Carla’s longest run of baskets on average, for 20 consecutive free throws. a) Describe a correspondence between random digits from the random number generator and outcomes.
Example: What is Let make = 0-7 and miss =8, 9?

On average, suppose a baseball player hits a home run once in every 10 times at bat, and suppose he gets exactly four "at bats" in every game. Using simulation, estimate the likelihood that the player will hit 2 home runs in a single game. 1.) Describe the possible outcomes. For this problem, there are two outcomes
What is: the player hits a home run or he doesn't?

1.Describe the possible outcomes. 2.Link each outcome to one or more random numbers. 3.Choose a source of random numbers. 4.Choose a random number. 5.Based on the random number, note the "simulated" outcome. 6.Repeat steps 4 and 5 multiple times; preferably, until the outcomes show a stable pattern. 7.Analyze the simulated outcomes and report results.
What are the steps required to run a simulation?

Wntering a command that would generate 10 numbers at a time from 0 - 99
What is the calculator command "ranInt (0, 99, 10) "

This models random events by using random numbers to specify event outcomes with relative frequencies that correspond to the true real-world relative frequencies we are trying to model.

Specifically Joey wants to use simulation methods to determine Carla’s longest run of baskets on average, for 20 consecutive free throws. b) What will constitute one repetition in this simulation?
What is “Shoot” 20 shots by looking at 20 random digits and count the longest run of makes?
200
On average, suppose a baseball player hits a home run once in every 10 times at bat, and suppose he gets exactly four "at bats" in every game. Using simulation, estimate the likelihood that the player will hit 2 home runs in a single game. Link each outcome to one or more random numbers. Since the player hits a home run in 10% of his at bats, 10% of the random numbers should represent a home run.
What is let the digit "2" represents a home run and any other digit represents a different outcome?
200
One event has no effect or influence over the next (e.g. coin tosses).
What is Independent?

A formula in which creates values
What is pseudo-random?

Specifically Joey wants to use simulation methods to determine Carla’s longest run of baskets on average, for 20 consecutive free throws. c) Starting with line 41 in the random digit table, carry out 10 repetitions and record the longest run for each repetition.
What is: Starting at Line 41, we have the following random digits for the first repetition of 20 shots:

On average, suppose a baseball player hits a home run once in every 10 times at bat, and suppose he gets exactly four "at bats" in every game. Using simulation, estimate the likelihood that the player will hit 2 home runs in a single game. 3) using a calculator to generate random numbers to conduct 10 trials. Show your numbers and state your conclusion.

Choose one person at random form a group of which 50% are employed, 20% are unemployed, and 30% are not in the labor force. There are now three possible outcomes, but the principle is the same. One digit simulates one person:
For example: What is 0, 1, 2, 3, 4 = employed 5, 6 = unemployed 7, 8, 9 = not in the labor force?
