Final Answer:
Two days of the last week had low temperatures lower than the average low temperature for the week, which was -1.5°F. So, the correct optionis Option 3: 2.
Step-by-step explanation:
To determine the number of days with temperatures lower than the average low for the week, I first calculated the average of the daily low temperatures. Summing the low temperatures of each day and dividing by seven yielded an average of -1.5°F for the week. Next, I assessed each day's low temperature against this average. Two days recorded temperatures below -1.5°F, indicating they were lower than the average low temperature for the week.
Throughout the week, the recorded low temperatures varied, impacting the overall average. By comparing each day's temperature to the weekly average of -1.5°F, it was evident that two days fell below this mark. This comparison establishes that only two days experienced low temperatures less than the average low for the entire week.
Understanding the frequency of days with temperatures below the weekly average is crucial in assessing the deviation from the norm. With the average low temperature set at -1.5°F, it becomes apparent that only two days out of the seven fell below this benchmark. This analysis clarifies that these two days exhibited lower temperatures than the week's average low temperature.
Considering the deviation of daily temperatures from the weekly average, two days stood out with temperatures below the -1.5°F mark. This comparison highlights the significance of understanding deviations from the average, revealing the specific count of days that experienced temperatures lower than the weekly average low of -1.5°F.
So, the correct optionis Option 3: 2.
