Minimum: 9 days q1: 18 days median: 21 days q3: 28 days maximum: 56 days if we use the 1.5 * iqr rule to determine whether there are any outliers, what is the right boundary?

To find the right boundary, we have to add 1.5 times the IQR to Q3.

... Q3 + 1.5(Q3 -Q1) = 28 + 1.5(28 -18) = 28 +15 = 43

The right boundary is 43.

Upper limit for boundary will be 43. (right side)

Lower limit or boundary will be 3. (left side)

Step-by-step explanation:

Given Five number summary:

Minimum: 9 days

: 18 days

Median: 21 days

: 28 days

Maximum: 56

Then IQR=

According to the 1.5 * IQR rule , the upper and lower limit for the boundary without outlier is given by :-

Upper limit=

Lower limit=

For the given situation,

Upper limit=

Lower limit=

2

step-by-step explanation:

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
