Answer:

3825

Step-by-step explanation:

Given that we have to pick digits from the list 1, 2, 3, 4, 5, 6, 7, 8, 9 just once and build 4 digit numbers.

Find the two numbers which have the sums as the smallest

Since when the two numbers formed are the smallest the sum will be the smallest, we can pick digits in such a ways that the numbers have value the smallest. If the 1000th digit is small we would get smaller number. So let us take for first digit 1000th place 1 and second number 1000th place as 2.

Similarly for 100th now available are 3,4...8, 9 so let us take 100th digit as 3 and 5 respectively and so on.

So the numbers would be

1357 and 2468

Sum would be $1357+2468 = 3825$

Answer:

The 5-number summary is maximum= 175, minimum=126, median=150, Q₁=138 and Q₃=160.5.

Step-by-step explanation:

The given data set is

126, 128, 131, 135, 136, 140, 143, 145, 147, 148, 152, 154, 155, 156, 159, 162, 164, 166, 169, 175

The minimum value of the data is 126 and the maximum value of the data is 175.

Divide the data in two equal parts.

(126, 128, 131, 135, 136, 140, 143, 145, 147, 148), (152, 154, 155, 156, 159, 162, 164, 166, 169, 175)

The median of the data is

$Median=\frac{148+152}{2}=150$

Now divide each parenthesis in two equal parts.

(126, 128, 131, 135, 136), (140, 143, 145, 147, 148), (152, 154, 155, 156, 159), (162, 164, 166, 169, 175)

$Q_1=\frac{136+140}{2}=138$

$Q_3=\frac{159+162}{2}=160.5$

Therefore the 5-number summary is maximum= 175, minimum=126, median=150, Q₁=138 and Q₃=160.5.
