Question

fernando has lived in fairbanks, alaska, for the past 10 years. one thing he loves about alaska is the long periods of daylight during the summer months. last june, there was a median of 21.5 hours of daylight in every 24 - hour period, with an interquartile range of 0.5 hours. on fathers day, there were 21.8 hours of daylight. what can you conclude from these data and statistics? select all that apply. a typical number of daylight hours for fairbanks last june was 24. fathers day had fewer hours of daylight than a typical day last june. the middle 50% of daylight hours last june had a range of 0.5 hours.

Explanation:

Step1: Recall median and IQR concepts

The median represents the middle - value. The inter - quartile range (IQR) represents the range of the middle 50% of the data.

Step2: Analyze option A

The median number of daylight hours in June was 21.5 hours, not 24 hours. So option A is incorrect.

Step3: Analyze option B

The median (a typical value) of daylight hours in June was 21.5 hours and on Father's Day there were 21.8 hours. So Father's Day had more hours of daylight than a typical day in June, and option B is incorrect.

Step4: Analyze option C

The inter - quartile range (IQR) is 0.5 hours. Since IQR represents the range of the middle 50% of the data, the middle 50% of daylight hours last June had a range of 0.5 hours. Option C is correct.

Answer:

C. The middle 50% of daylight hours last June had a range of 0.5 hours.
