 The average family size in the Philippines was reported as 4.25. A random of families in a particular street resulted in the following family sizes: 5, 6, 7, 4, 3, 2, and 9. At 𝛼=0.10, does the average family size more than the national average?



a.

Explain how you could use the random number table shown below to simulate rolling a fair​ six-sided die. Assume you are interested in the probability of rolling a 4.

b.

Using the random number table​ below, report the empirical probability of rolling a 4 on the​ six-sided die from part​ a, and compare it with the theoretical probability of rolling a 4.

1​, 5​, 4​, 9​, 1​, 3​, 3​, 7​, 6​, 2  

4​, 5​, 9​, 6​, 8​, 5​, 2​, 4​, 4​, 8

a. Which of the following is the best explanation on how to use the random number table to simulate rolling the​ die?


Use all the numbers in the random number table.

b. The empirical probability of rolling a 4 is and The theoretical probability of rolling a 4 is

Explain how you could use the random number table shown below to simulate rolling a fair​ six-sided die. Assume you are interested in the probability of rolling a 2.

b.

Using the random number table​ below, report the empirical probability of rolling a 2 on the​ six-sided die from part​ a, and compare it with the theoretical probability of rolling a 2.

1​, 8​, 4​, 6​, 2​, 0​, 1​, 8​, 8​, 6  

2​, 9​, 6​, 2​, 6​, 2​, 4​, 8​, 1​, 1

a. Which of the following is the best explanation on how to use the random number table to simulate rolling the​ die?


Use the numbers​ 1, 2,​ 3, 4,​ 5, and 6 to represent the outcomes and ignore 0 and​ 7-9.

At a school raffle, students can purchase two types of tickets: Ticket A which costs $2.00 each, students can win the following prizes: twenty $10 Tim Horton's gift cards, twelve $15 Starbucks' gift cards, and five $30 Staples gift cards. Ticket B which costs $3.00 each, students can win the following prizes: three $25 Tim Horton's gift cards, and two $300 Staples gift card. Suppose there are only 600 of each types of tickets being sold.

a) Complete a probability distribution table for each ticket.

b) Determine which type of raffle ticket has greater value. Justify your answer.

A store had a scratch-and-win promotion in which 1000 cards indicated 10% off, 50 cards indicated 15% off, 10 cards indicated 20% off and 1 card indicated 40% off. What is the expected value for a given scratch-and-win card? *


A civic organization includes 200 members, who have an average income of $58,000, with a standard deviation of $10,000. A simple random sample of n 5 30 members is selected to participate in the annual fund-raising drive. What is the probability that the average income of the fund-raising group will be at least $60,000?
