Chapter 4.5, Problem 4ED

a.

To determine

Identify whether the SD is around 1, 2, or 10 for the given list.

a.

Expert Solution

Answer to Problem 4ED

The SD is around 1.

Explanation of Solution

Calculation:

The average of the given list is 50.

The difference between the given observations and the average is,

Deviations={(49−50),(51−50),(49−50),(51−50),(49−50),(51−50),(49−50),(51−50),(49−50),(51−50)}=(−1,1,−1,1,−1,1,−1,1,−1,1)

Here, all deviations from the average is ±1.

Therefore, the SD is around 1.

Expert Solution

Answer to Problem 4ED

The SD is around 2.

Explanation of Solution

Calculation:

The average of the given list is 50.

Condition:

If the spread of the numbers around the average is larger, then the value of SD is larger.
If the spread of the numbers around the average is smaller, then the value of SD is smaller.

The difference between the given observations and the average is,

Deviations={(48−50),(51−50),(49−50),(52−50),(47−50),(52−50),(46−50),(51−50),(53−50),(51−50)}=(−2,1,−1,2,−3,2,−4,1,3,1)

Here, the given data set has less spread. Hence, the SD is around 2.

Expert Solution

Answer to Problem 4ED

The SD is around 2.

Explanation of Solution

Calculation:

To determine

Identify whether the SD is around 1, 2, or 10 for the given list.

e.

Expert Solution

Answer to Problem 4ED

The SD is around 10.

Explanation of Solution

Calculation:

The average of the given list is 50.

The difference between the given observations and the average is,

Deviations={(60−50),(36−50),(31−50),(50−50),(48−50),(50−50),(54−50),(56−50),(62−50),(53−50)}=(10,−14,−19,0,−2,0,4,6,12,3)

Here, the spread of the numbers around the average is larger. This provide the largest SD.

Therefore, the SD is around 10.

Pam, Rob and Sam get a cake that is one-third chocolate, one-third vanilla, and one-third strawberry as shown below. They wish to fairly divide the cake using the lone chooser method. Pam likes strawberry twice as much as chocolate or vanilla. Rob only likes chocolate. Sam, the chooser, likes vanilla and strawberry twice as much as chocolate. In the first division, Pam cuts the strawberry piece off and lets Rob choose his favorite piece. Based on that, Rob chooses the chocolate and vanilla parts. Note: All cuts made to the cake shown below are vertical.Which is a second division that Rob would make of his share of the cake?

Three players (one divider and two choosers) are going to divide a cake fairly using the lone divider method. The divider cuts the cake into three slices (s1, s2, and s3). If the choosers' declarations are Chooser 1: {s1 , s2} and Chooser 2: {s2 , s3}. Using the lone-divider method, how many different fair divisions of this cake are possible?

Calculation:

The average of the given list is 50.

The difference between the given observations and the average is,

Deviations={(60−50),(36−50),(31−50),(50−50),(48−50),(50−50),(54−50),(56−50),(62−50),(53−50)}=(10,−14,−19,0,−2,0,4,6,12,3)
