standard_description: Write an inequality of the form x > c or x < c to represent a constraint or condition in a real-world or mathematical problem. Recognize that inequalities of the form x > c or x < c have infinitely many solutions; represent solutions of such inequalities on number line diagrams.

Each of the 20 students in Mr. Anderson's class timed how long it took them to solve a puzzle. Their times (in minutes) are listed below:
{"table": [{"tbody": [{"tr": [{"th": [{"_value": "Student"}], "td": [{"_value": "1"}, {"_value": "2"}, {"_value": "3"}, {"_value": "4"}, {"_value": "5"}, {"_value": "6"}, {"_value": "7"}, {"_value": "8"}, {"_value": "9"}, {"_value": "10"}, {"_value": "11"}, {"_value": "12"}, {"_value": "13"}, {"_value": "14"}, {"_value": "15"}, {"_value": "16"}, {"_value": "17"}, {"_value": "18"}, {"_value": "19"}, {"_value": "20"}]}, {"th": [{"_value": "Time (minutes)"}], "td": [{"_value": "3"}, {"_value": "5"}, {"_value": "4"}, {"_value": "6"}, {"_value": "4"}, {"_value": "8"}, {"_value": "5"}, {"_value": "4"}, {"_value": "9"}, {"_value": "5"}, {"_value": "3"}, {"_value": "4"}, {"_value": "7"}, {"_value": "5"}, {"_value": "8"}, {"_value": "6"}, {"_value": "3"}, {"_value": "6"}, {"_value": "5"}, {"_value": "7"}]}]}]}]}
Display the data using a dot plot.
Find the mean and median of the data. Does it surprise you that the values of the mean and median are not equal? Explain why or why not.
