Answer:
(a)High school students in the United States.
(b)100 Students
(c)Statistic
Step-by-step explanation:
(a)Since the researcher is interested in the texting habits of high school students in the United States, the population for this study consists of all high school students in the United States.
(b)It is most often improbable to carry out research on an entire population of study. A <u>sample is taken to represent the population</u> and the results obtained from the sample are assumed to hold for the entire population.
In the given study, the researcher selects a group of 100 students to represent the High School students in the United States. This is the sample for the study.
(c)The researcher calculated the average number of text messages that each individual sends each day from the sample of 100 Students. This is an example of a Statistic. A statistic is a numerical data obtained from a sample.
Note: If the data were obtained from the entire population, it would be a <u>parameter.</u>
A circular pool with a diameter of 18 ft will have a uniform
4 ft concrete walkway poured around it. If the concrete cost $4.25 a square
foot, how much will it cost for the concrete?
This can be solve be solving the area of walkway
Area of walkway is equal to = (pi)( 9 ft +4) ^2– (pi)(9ft)^2
= 276.46 sq ft
Cost = 276.46 sq ft * ($4.25 a square foot) = $1174.70
Answer:
(a) 0.873 (b) 0.007 (c) 0.715 (d) 0.277 (e) 1.25 and 1.09
Step-by-step explanation:
The probability that the random variable X takes the value x is given by P(X=x) = 
. Then,
(a) 
(b) 
(c) 
(d) 
(e) E(X) = np = (25)(0.05) = 1.25 and
