Question

suzie read that a persons average body temperature is 98.6°f. she also read that a persons body temperature changes throughout the day. suzie took her temperature several times throughout the day yesterday. this table shows how her body temperature compared to the average body temperature of 98.6°f.

time	temperature (°f above or below average)
11:00 a.m.	-0.3
1:30 p.m.	0.4
5:00 p.m.	1.1
8:30 p.m.	0.2

pick all the true statements.

her temperature at 1:30 p.m. was lower than her temperature at 5:00 p.m.

her temperature at 7:30 a.m. was higher than her temperature at 8:30 p.m.

her temperature was lowest at 8:30 p.m.

her temperature was highest at 5:00 p.m.

Explanation:

Step1: Analyze temperature at 1:30 p.m. and 5:00 p.m.

At 1:30 p.m., temperature is 0.4°F above average. At 5:00 p.m., temperature is 1.1°F above average. Since 0.4 < 1.1, temperature at 1:30 p.m. is lower than at 5:00 p.m.

Step2: Analyze temperature at 7:30 a.m. and 8:30 p.m.

At 7:30 a.m., temperature is - 0.8°F below average. At 8:30 p.m., temperature is 0.2°F above average. -0.8 < 0.2, so temperature at 7:30 a.m. is lower than at 8:30 p.m., this statement is false.

Step3: Find the lowest - temperature time

The values are -0.8, - 0.3, 0.4, 1.1, 0.2. The lowest value is -0.8 which corresponds to 7:30 a.m., so temperature is not lowest at 8:30 p.m., this statement is false.

Step4: Find the highest - temperature time

Among -0.8, - 0.3, 0.4, 1.1, 0.2, the highest value is 1.1 which corresponds to 5:00 p.m., so temperature is highest at 5:00 p.m.

Answer:

Her temperature at 1:30 p.m. was lower than her temperature at 5:00 p.m.; Her temperature was highest at 5:00 p.m.
