Chapter 1, Problem 1.39RE

a)

To determine

To give the list of the question of interest.

Explanation of Solution

Given:

According to scientists, a typical cow burps about every 40 seconds. When cows burp, they release methane gas that is built up while digesting their food. Some estimates suggest that livestock produce over 25% of methane emissions each year. Researchers in Germany have developed a pill that is designed to reduce the amount of methane that cows produce.

The researcher developed a pill that is designed to reduce the amount of methane that cows produce. That means it is need to observe that how often cow burp after taking that pill.

Hence, question is “How often does a cow burp when taking the pill?”

b)

To determine

To explain design a study to answer the question of interest.

Explanation of Solution

Given:

According to scientists, a typical cow burps about every 40 seconds. When cows burp, they release methane gas that is built up while digesting their food. Some estimates suggest that livestock produce over 25% of methane emissions each year. Researchers in Germany have developed a pill that is designed to reduce the amount of methane that cows produce.

The question is “How often does a cow burp when taking the pill?” To answer this question, first need to select rando group in which it will be divided into two groups. For first group pill is used and second group it is not used. Now we can compare the burps of cows for both groups.
