Chapter 1, Problem 1.1HD
A father rates his daughter as a 2 on a 7-point scale (from 1 to 7) of crankiness. In this example, (a) what is the variable, (b) what is the score, and(c) what is the
a.
Expert Solution
To determine
Identify the variable.
Answer to Problem 1.1HD
The variable is level of crankiness.
Explanation of Solution
Variable:
A variable is a characteristic or a condition of the subject under study, which can take several values.
The characteristic under study is the level of crankiness of the daughter, as decided by the father.
b.
Expert Solution
To determine
Identify the score.
Answer to Problem 1.1HD
The score is 2.
Explanation of Solution
The father provided a score of 2 on crankiness to his daughter. Thus, the score is 2.
c.
Expert Solution
To determine
Identify the range of the variable.
Answer to Problem 1.1HD
The range of the variable is 1 to 7.
Explanation of Solution
The crankiness score may take values between 1 and 7, on a 7-point scale. The minimum possible value on the scale is 1 and the maximum possible value is 7. Thus, the range of the variable is 1 to 7.

Suppose that you want to estimate the mean monthly gross income of all households in your local community. You decide to estimate this population parameter by calling 150 randomly selected residents and asking each individual to report the household’s monthly income. Assume that you use the local phone directory as the frame in selecting the households to be included in your sample.
What are some possible sources of error that might arise in your effort to estimate the population mean?
For the distribution shown, match the letter to the measure of central tendency.

A physician who has a group of 38 female patients aged 18 to 24 on a special diet wishes to estimate the effect of the diet on total serum cholesterol. For this group, their average serum cholesterol is 188.4 (measured in mg/100mL). Suppose that the total serum cholesterol measurements are normally distributed with standard deviation of 40.7. (a) Find a 95% confidence interval of the mean serum cholesterol of patients on the special diet.
