Oklahoma State Officials. Refer to Table 5.1 on page 196.

(a). List the possible samples without replacement of size 3 that can be obtained from the population of five officials. (Hint: There are 10 possible samples.)

If a simple random sample without replacement of three officials is taken from the five officials, determine the probability that

(b). the governor, attorney general, and treasurer are obtained.

(c). the governor and treasurer are included in the sample.

Step by step solution

01

Part (a) Step 1. Given information.

The given statement is:

The given table 5.1 is on page 196 is shown below:

02

Part (a) Step 2. List the possible samples without replacement of size 3 that can be obtained from the population of five officials.

In each sample, only one official can be chosen at a time.

As a result, the following consequences are possible:

GLS,GLA,GLT,GAT,GSA,GST,LSA,LST,SAT,LAT

03

Part (b) Step 1. Determine the probability that the governor, attorney general, and treasurer are obtained if a simple random sample without replacement is taken.

A simple random sample with no replacement is utilized to choose the three of the five officials.

The number of positive outcomes divided by the total number of possible outcomes is the likelihood.

GAT is a possible consequence out of a total of ten possible outcomes.

As a result, a sample of the governor, attorney general, and treasurer has a chance of:

110=0.1.

04

Part (c) Determine the probability that the governor and treasurer are included in the sample.  

Possible outcomes of the probability that the governor and treasurer are:

GLT, GST, GAT

As a result, a sample that includes the governor and treasurer has a probability of:

310=0.3

05

Part (d) Determine the probability that the governor is included in the sample.

Possible outcomes of the probability that the governor and treasurer are:

GLS, GLA, GLT, GAT, GSA, GST

As a result, a sample that includes the governor is included in the sample has a probability of:

610=0.6

Penalty Kicks. In the game of soccer, a penalty kick is a direct free kick, taken from 12 yards out from the goal on the penalty mark. According to the article "Penalty Kicks in Soccer: An Empirical Analysis of Shooting Strategies and Goalkeeper's Preferences" (Soccer & Society, Vol. 10, No. 2. pp. 183-191) by M. Bar-Eli and O. Azar, 85% of penalty kicks placed by professional soccer players are successful. In 15 penalty kicks by professional soccer players, what is the probability that

(a) all are successful?

(b) at least 13 are successful?

(c) Find and interpret the mean and standard deviation of the number of successful penalty kicks out of 15.
