Concept explainers
To find: The individuals and variables using the provided table. Also, classify the variables a as categorical or quantitative.
Answer to Problem 44E
There are total 7 individuals.
Explanation of Solution
Given:
The table is:
In the table, the first column is representing the individuals. Thus, 7 hotels are the individuals.
Rest of the columns are the variables. It means the pool, exercise room, internet, room rate, distance to site, restaurants and room service are the variables.
There are two categories for the variable pool, that is, In and Out. Thus, it is a categorical variable.
Similarly, the variable exercise room also has two categories, that is, Y and N. Thus, it is also a categorical variable.
The variable ‘distance to site” gives the distance travelled. The unit of this variable is miles. As the values of the variable are the measured quantities, the variable ‘distance to siteis a numerical variable.
The variable ‘restaurants’ represents the counts. The units are just the number of restaurants eachhotel has. As the values of the variable are the measured quantities, the variable ‘restaurants’ is a numerical variable. Also, the variables room rate and internet are the numerical variables.
And, there are 3 categories for the variables Y, N and Dinner. Thus, it is a categorical variable.

- Use StatCrunch to solve.arrow_forwardBased on a poll, among adults who regret getting tattoos, 18% say that they were too young when they got their tattoos. Assume that eight adults who regret getting tattoos are randomly selected, and find the indicated probability. Complete parts (a) through (d) below. a. Find the probability that none of the selected adults say that they were too young to get tattoos. (Round to four decimal places as needed.) b. Find the probability that exactly one of the selected adults says that he or she was too young to get tattoos. (Round to four decimal places as needed.) c.
