Eli, Justin, Harry, and Paris each conducted surveys on how many pets their neighbors had in their homes. Each student determined the accuracy of the following statement.

"All measures of central tendency must appear as a number in the set of data collected."

Which student's statement is CORRECT?

• Eli says this is sometimes true because the mean and median may or may not be visible in the set of data, but the mode is always visible if present.

• Justin says this is sometimes true because the mean and mode may or may not be visible in the set of data, but the median is always in the set of data.

• Harry says this is always true because all the measures of central tendency also have to be numbers that are visible in the data set.

• Paris says this is never true because all the measures of central tendency are never number that are visible in the set of data

Jalen says that 60% of his teammates are over 70 inches. Is Jalen’s statement correct?

73, 61, 62, 59, 75, 60, 74, 75, 78, 69, 70

• No, because there are 5 players with a height greater than 70 inches and that’s about 55% of the players

• Yes, there are at least 9 players with a height of at least 70 inches and that is 60% of the players.

• No, there is one player with a height of 70 inches and that is 9% of his teammates.

• Yes, because the median height of the ponies is 60 and 60% of the ponies would be taller.
