Answer:

The new IQR is 22.

Step-by-step explanation:

We are given the following data of length (in mm) of 12 soybean plants after 3 days of sprouting.

53, 47, 51, 54, 43, 39, 61, 57, 55, 46, 44, 43

Sorted data:

39, 43, 43, 44, 46, 47, 51, 53, 54, 55, 57, 61

Formula:

$IQR = Q_3 - Q_1\\Q_3 = \text{upper median},\\Q_1 = \text{ lower median}$

$Median:\\\text{If n is odd, then}\\\\Median = \displaystyle\frac{n+1}{2}th ~term \\\\\text{If n is even, then}\\\\Median = \displaystyle\frac{\frac{n}{2}th~term + (\frac{n}{2}+1)th~term}{2}$

$Median ==\dfrac{6^{th}+7^{th}}{2} \dfrac{47+51}{2} = 49$

$Q_1 =\dfrac{3^{rd}+4^{th}}{2} = \dfrac{43 + 44}{2} = 43.5\\\\Q_3 =\dfrac{9^{th}+10^{th}}{2}= \frac{54 + 55}{2} = 54.5$

IQR = $Q_3 -Q_1 =54.5-43.5= 11$

If every measurement is doubled, then, the IQR will also double itself.

Thus,

New IQR =

$2\times \text{IQR}\\=2\TIMES 11\\=22$

Thus, the new IQR is 22.

Maureen spends four times as long riding the train each day as riding the bus. If she spends 75 minutes on the bus and the train

yulyashka [42]

Answer:

60 minutes or 1 hour

Step-by-step explanation:

Set x as the amount of time she spends riding the bus

75 = time on bus + time on train

She spends 4 times as long on the train as on the bus so the time she spends on the train is 4x

75 = x + 4x

75 = 5x

x = 15 minutes on the bus

Since she spends 4 times as long on the train, we do 4 x 15 and we get 60 minutes which is 1 hour
