Elena would like to know the average height of seventh graders in her
school district. She measures the heights of everyone in a random
sample of 20 students. The mean height of Elena's sample is 58 inches,
and the MAD (mean absolute deviation) is 3 inches.
Select all the true statements.

The mean height of all seventh graders is likely be between 52 and 64 inches.

Another random sample of 20 students will always have a mean of 58 inches.

A sample of 20 female students would be more likely to get an accurate estimate of the
mean height of the population than a sample of a mix of 20 male and female students.

A sample of 100 seventh graders would be more likely to get an accurate estimate of the
mean height of the population than a sample of 20 seventh graders.

Elena's sample proves that half of all seventh graders are taller than 58 inches.

PLEASE HELP!!! 20 POINTS WILL VOTE BRAINLIEST IF CORRECT!!!!!!!!
