In order to estimate the typical amount of TV watched per day by students at her school of 932 students, a student has all of the students in her statistics class ( students) take a short survey, finding that, on average, students in her statistics class report watching hours of television per day.

1) Quantitative

2) a) Mean or Median

3) b) Bar graph

Step-by-step explanation:

The question is incomplete:

"In order to estimate the typical amount of TV watched per day by students at her school of 932 students, a student has all of the students in her statistics class (30 students) take a short survey, finding that, on average, students in her statistics class report watching 1.2 hours of television per day.

1 - Is the varlable categorical or quantitative?

2 - Identlfy two statistics that the student could use to summarize the variable.

a) Mean or Median b) Mean or Proportions c) Mean or Mode d) Median or Mode.

3 - Identify one graph that the student could use to summarize the variable.

a) Line graph b) Bar graph  c) Dotplot d) Pie chart e) Scatter Plot

1) The variable is quantitative as it is a number and we can perform meaningful numerical operations with it.

2) The mean is the most appropiate statistic to summarize the variable.

Proportions is not adequate.

Mode is not appropiate as we are probably dealing with a continous variable.

The second most appropiate is the median, as it is appropiate for continous values for the variable.

3) If he classifies the result in classes, he can chart the results in a bar graph.

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
