Answer:

B and c and also f is the answer

1st Period: Minimum = 60, Lower Quartile = 75, Median = 80, Upper Quartile = 90, Maximum = 98

* Range = 98-60 = 38; *Interquartile Range = 90-75 = 15

2nd Period: Minimum = 70, Lower Quartile = 80, Median = 85, Upper Quartile = 91, Maximum = 95

* Range = 95-70 = 25; *Interquartile Range = 91-70= 21

Correct Answers: B, C, F

B - lowest score was a 60 in first period

What is statistics?

The practice or science of collecting and analysing numerical data in large quantities, especially for the purpose of inferring proportions in a whole from those in a representative sample.

1st Period: Minimum = 60, Lower Quartile = 75, Median = 80, Upper Quartile = 90, Maximum = 98

* Range = 98-60 = 38; *Interquartile Range = 90-75 = 15

2nd Period: Minimum = 70, Lower Quartile = 80, Median = 85, Upper Quartile = 91, Maximum = 95

* Range = 95-70 = 25; *Interquartile Range = 91-70= 21

Hence the solutions are:-

B - lowest score was a 60 in first period

C - IQR in 2nd period is 21, which is higher than 15 in first period

F - Approximately 75% (Q1-Q3) of first period scores are higher than 75% (Q1-Q3) of second period.
