Final answer:
The median temperature is determined by ordering the two-week range of temperatures and averaging the seventh and eighth values from this ordered list.
Step-by-step explanation:
The question involves finding the median temperature from a set of daily low temperatures over a period of two weeks in December. To find the median, we first need all the temperatures listed in numerical order. Since there are 14 observations, which is an even number, the median will be the average of the seventh and eighth temperatures in this ordered list. If,
for example, the seventh temperature is 6.8 degrees and the eighth temperature is 7.2 degrees, we would find the median by adding these two temperatures together and dividing by two, resulting in a median temperature of 7.0 degrees.
