Analyzing Data Sets and Inequalities

This video tutorial covers the use of histograms to answer statistical questions. It includes comparing text message data from sixth and seventh graders, creating a histogram for running times with less variability, solving inequalities related to the number of dimes, and ordering numbers from greatest to least. The lesson concludes with a summary of the key points covered.

What is the center value of the data sets for both sixth and seventh graders?

• 90

• 95

• 105

• 100

Which grade's data set has a greater spread?

• Cannot be determined

• Both have the same spread

• Sixth grade

• Seventh grade

What is the range of the sixth grade data set?

• 45 to 125

• 45 to 155

• 75 to 125

• 75 to 155

Do sixth graders or seventh graders send more text messages overall?

• Seventh graders

• Sixth graders

• Cannot be determined

• Both send the same amount

What is the center of the distribution for the new histogram?

• 8 minutes

• 9 minutes

• 10 minutes

• 11 minutes

What is the range of the new histogram's variability?

• 4 to 16

• 6 to 14

• 5 to 15

• 7 to 13

Which inequality correctly represents the number of dimes Jada has?

• d > 3

• d < 10

• d <= 9

• d >= 4

Can Jada have 10 dimes?

• Only if she has less than 30 cents

• Yes

• No

• Only if she has more than a dollar

How many possible solutions exist for the inequalities regarding Jada's dimes?

• Six

• Five

• Seven

• Four

Order these numbers from greatest to least: 4, 7, 4.1, 4.0, -5.4, -3.5, -4.

• 7, 4.1, 4.0, 4, -3.5, -4, -5.4

• 4.1, 7, 4.0, 4, -3.5, -4, -5.4

• 7, 4, 4.1, 4.0, -3.5, -4, -5.4

• 7, 4.1, 4, 4.0, -3.5, -4, -5.4
