Chapter 3: Q. 106 (page 227)

Use the information in the Table 3.19to answer the next eight exercises. The table shows the political party affiliation of each of 67members of the US Senate In June 2012. and when they are up freelection.

Suppose that a member of the US Senate is randomly selected. what is the probability that the senator Is up for reelection in November 2014, knowing that this senator is a Republican?

Short Answer

Expert verified

The probability of the reelection in November 2014 , where the senator is a Republican isP(R)=0.35.

Step by step solution

01

Given

The table shows the political party affiliation of each of 67members of the US Senate In June 2012. and when they are up freelection.

02

Calculation  

The total as:

The chance of reelection in November 2014 for a Republican senator is computed as :

Let the probability be R.

P(R)=n(R)n(S)n(R)=13;n(S)=37P(R)=1337=0.35

After Rob Ford, the mayor of Toronto, announced his plans to cut budget costs in late 2011, the Forum Research polled 1,046people to measure the mayor鈥檚 popularity. Everyone polled expressed either approval or disapproval. These are the results their poll produced:

鈥� In early 2011,60percent of the population approved of Mayor Ford鈥檚 actions in office.

鈥� In mid-2011,57percent of the population approved of his actions.

鈥� In late 2011, the percentage of popular approval was measured at 42percent.

a. What is the sample size for this study?

b. What proportion in the poll disapproved of Mayor Ford, according to the results from late 2011?

c. How many people polled responded that they approved of Mayor Ford in late 2011?

d. What is the probability that a person supported Mayor Ford, based on the data collected in mid-2011?

e. What is the probability that a person supported Mayor Ford, based on the data collected in early 2011?

What is the word for the set of all possible outcomes?

Roll a fair, six-sided die. Let A = a prime number of dots is rolled. Let B = an odd number of dots is rolled. Then A = {2, 3, 5} and B = {1, 3, 5}. Therefore, A AND B = {3, 5}. A OR B = {1, 2, 3, 5}. The sample space for rolling a fair die is S = {1, 2, 3, 4, 5, 6}. Draw a Venn diagram representing this situation.

When the Euro coin was introduced in 2002, two math professors had their statistics students test whether the Belgian one Euro coin was a fair coin. They spun the coin rather than tossing it and found that out of 250spins,140showed a head (event H) while 110showed a tail (event T). On that basis, they claimed that it is not a fair coin.

a. Based on the given data, find P(H) and P(T).

b. Use a tree to find the probabilities of each possible outcome for the experiment of tossing the coin twice.

c. Use the tree to find the probability of obtaining exactly one head in two tosses of the coin.

d. Use the tree to find the probability of obtaining at least one head
