Chapter 1: Q 50. (page 48)

Pair-a-dice The dotplot shows the results of rolling a pair of fair, six-sided dice and Page Number: 48 finding the sum of the up-faces 100 times. Describe the shape of the distribution.

Short Answer

Expert verified

Roughly symmetric

Single peak

No gaps

Step by step solution

01

 Step 1. Given information.

The dotplot shows the results of rolling a pair of fair, six-sided dice and Page Number: 48 finding the sum of the up-faces 100 times.

02

 Step 2. The shape of the distribution.  

Because the peak in the dotplot is roughly in the middle of the graph, we can conclude that the distribution is roughly symmetric.

We notice that the distribution has a single peak at 7, and there appear to be no gaps in the dotplot.

Roughly symmetric

Single peak

No gaps

Part (b). What variables were measured? Classify each as categorical or quantitative.

Python eggs How is the hatching of water python eggs influenced by the temperature of the snake鈥檚 nest? Researchers randomly assigned newly laid eggs to one of three water temperatures: hot, neutral, or cold. Hot duplicates the extra warmth provided by the mother python, and cold duplicates the absence of the mother. The two-way table summarizes the data on whether or not the eggs hatched.

(a) What percent of eggs were randomly assigned to hot water?

(b) What proportion of eggs in the study hatched?

(c) What percent of eggs in the study were randomly assigned to cold or neutral water and hatched?
