e shows the monthly data usage in gigabytes for two cell on a family plan.
complete the statements.
the range of data usage for the primary phone is \boxed{} gigabytes.
the range of data usage for the secondary phone is \boxed{} gigabytes.
the median data usage of the secondary phone is \boxed{} gigabytes greater than the median data usage of the primary phone.

month	primary phone	secondary phone
february	0.07	1.18
march	0.1	0.6
april	0.13	0.5
may	0.12	0.45
june	0.14	0.82
july	0.35	0.91
august

Explanation:

Part 1: Range of Primary Phone Data Usage

Step 1: Identify Min and Max for Primary

From the table, primary phone data (in GB) values: 0.08, 0.07, 0.1, 0.13, 0.12, 0.14, 0.35 (assuming August is cut off, but visible data: min = 0.07, max = 0.35).

Step 2: Calculate Range

Range = Max - Min = \( 0.35 - 0.07 = 0.28 \).

Part 2: Range of Secondary Phone Data Usage

Step 1: Identify Min and Max for Secondary

Secondary phone data: 0.45, 1.18, 0.6, 0.5, 0.45, 0.82, 0.91 (visible). Min = 0.45, Max = 1.18.

Step 2: Calculate Range

Range = \( 1.18 - 0.45 = 0.73 \).

Part 3: Median Comparison

Step 1: Median of Primary (sorted: 0.07, 0.08, 0.1, 0.12, 0.13, 0.14, 0.35)

Median (middle term) = 0.12.

Step 2: Median of Secondary (sorted: 0.45, 0.45, 0.5, 0.6, 0.82, 0.91, 1.18)

Median = 0.6.

Step 3: Difference

Difference = \( 0.6 - 0.12 = 0.48 \).

Answer:

s:

• Range of primary phone: \( \boldsymbol{0.28} \)
• Range of secondary phone: \( \boldsymbol{0.73} \)
• Median difference: \( \boldsymbol{0.48} \)
