Question

the stem - and - leaf plot shows the number of days of snowfall at a winter sports resort for each of the past 17 years. stem | leaf 5 | 0 7 6 | 2 4 5 5 8 7 | 0 1 2 3 4 7 9 9 key: 6 | 2 represents a year with 62 days of snowfall. here is the five - number summary for these data: five - number summary min $q_1$ median $q_3$ max 50 64.5 70 78.5 79 according to the 1.5 - iqr rule for outliers, how many high outliers are there in the data set? choose 1 answer:

Explanation:

Step1: Calculate the inter - quartile range (IQR)

$IQR = Q_3 - Q_1$. Given $Q_1 = 64.5$ and $Q_3 = 78.5$, so $IQR=78.5 - 64.5=14$.

Step2: Calculate the upper fence for outliers

The upper fence for outliers is $Q_3+1.5\times IQR$. Substitute the values: $78.5+1.5\times14 = 78.5 + 21=99.5$.

Step3: Check the data values

The maximum value in the data set is $79$. Since $79<99.5$, there are no high outliers.
