I °F

Answer 1

To find an outlier in a set of temperature data, calculate the interquartile range and determine values outside of the range

Step-by-step explanation:

To identify the outlier in a set of data, we can use the five-number summary and the concept of outliers. The five-number summary includes the minimum, first quartile (Q1), median, third quartile (Q3), and maximum. To determine outliers, we can use the interquartile range (IQR) which is found by subtracting Q1 from Q3. We then look for values that are below Q1 - 1.5 * IQR or above Q3 + 1.5 * IQR. In this case, the temperatures that fall outside this range are 87 and 76. Therefore, the outlier temperature is 87°F.
