A student read the triple beam balance below and recorded the mass as 100.7 grams. What mistake did she make, and what is the correct mass?
She misread the tenths place; the correct mass is 101.7 grams.
She added the riders incorrectly; the correct mass is 100.0 grams.
She ignored the hundreds place; the correct mass is 200.7 grams.
She read the balance backwards; the correct mass is 70.1 grams.

Calculate the average number of male and female patients admitted to the hospital.
Average for males: (2+6+9+11+8+15)/6 = 8.5; Average for females: (5+8+5+14+7+9)/6 = 8
Average for males: (2+6+9+11+8+15)/6 = 7.5; Average for females: (5+8+5+14+7+9)/6 = 7
Average for males: (2+6+9+11+8+15)/6 = 9.5; Average for females: (5+8+5+14+7+9)/6 = 9
Average for males: (2+6+9+11+8+15)/6 = 10.5; Average for females: (5+8+5+14+7+9)/6 = 10
What is the range for males?
Range for males: 15 - 2 = 13
Range for males: 20 - 5 = 15
Range for males: 18 - 3 = 15
Range for males: 14 - 4 = 10
On what day did the hospital admit the most patients?
Day 4 (11 males + 14 females = 25 patients)
Day 2 (8 males + 10 females = 18 patients)
Day 1 (7 males + 9 females = 16 patients)
Day 3 (9 males + 12 females = 21 patients)
On what day was there the biggest difference between the number of male and female patients admitted?
Day 6
Day 2
Day 4
Day 5
There is a trend or pattern in the data. Why or why not?
Yes, there is a trend because the data shows a consistent increase or decrease.
No, there is no trend because the data is completely random.
Yes, there is a trend because the data points are all the same value.
No, there is no trend because the data is missing values.
