vlabodo [156]

Answer:

(a)High school students in the United States.

(b)100 Students

(c)Statistic

(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.

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.

-2/3-5/6= write in simplest form
sleet_krkn [62]
-2/3 - 5/6 

We need common denominators so, since 3 can go into 6, we only need to multiply the first fraction by 2.

= -2 x 2 / 3x2  -  5/6 
= -4 / 6 - 5/6 
 
We only subtract the numbers that are in the numerators, 

= -4-5 / 6 
= -9/6 

Both nine and six are divisible by 3, so to put into lowest terms... 

=-9÷3 / 6÷3
= -3/2  <--- Final Answer
