Marvin's grades currently in math are 100, 97, 98, 74, and 85. Gavin's grades currently in math are 98, 100, 88, 91, and 65. Which student has the highest mean score?

• Marvin

• Gavin

Marvin's grades currently in math are 100, 97, 98, 74, and 85. Gavin's grades currently in math are 98, 100, 88, 91, and 65. Find the range of each student's scores and make an inference about their ranges.

Four fourth-grade girls and four seventh-grade girls were randomly selected. Their heights, in inches, are recorded below.

4th Grade

56, 47, 54, 51

7th Grade

57, 58, 60, 64

What is the mean for 7th grade?

• 59.75

• 58

• 60

• 52

If Mr. Estes looked at the means (averages) for the last SAFE Quiz for his classes, and the averages were 72%, 71%, and 74%, what inference can you make based on those averages?
