Question

2. A smartphone manufacturer is advertising that its new smartphone has the best battery life. Thirty smartphones were
randomly selected and the number of hours each smartphone lasted before reaching 0% battery is recorded below.
A. Using the following distribution of battery life (in hours) of the latest new smartphone, construct a box & whisker plot
on the graph paper and display the 5-number summary on the boxplot.
BATTERY LIFE (IN NUMBER OF HOURS)
50, 25, 39, 37, 49, 48, 62, 44, 41, 34, 38, 39, 40, 49, 32, 36, 44, 49, 47, 44, 49, 46, 39, 38, 44, 45, 50, 43, 40, 42
(Σ- 1233 εnd Σx-56261 )
B. State the 5-Number Summary:
Lower Quartile:
Median:
Upper Quartile:
Min:
Мах:
C. State the shape of the Box Plot.
D. What does the shape of the Box Plot indicate about the battery lives of the new smartphone?
E. Using the modified box plot function of your TI Calculator modified box plot, determine if there are any outliers or
potential outliers. If outlier(s) exist, then state the value of the outlier(s).
