Question

  1. sampling percent: what percentage of the total number of u.s. adults did the harris poll sample for its survey? (assume the number of u.s. adults is 257.9 million)

0.7579%
0.0132%
0.0001%
0.0076%

  1. nominal level of measurement: identify any column in the table with data at the nominal level.

year company formed
reputation
industry
number of employees
none of the above

Explanation:

Step1: Assume sample size

Since the sample size is not given in the problem, we cannot calculate the percentage for the first - question. For the second question, we use the concept of nominal level of measurement.

Step2: Recall nominal level definition

Nominal level of measurement is used for categorical data where the categories have no inherent order.

Step3: Analyze each option

  • "Year Company Formed" is a numerical value representing time and has an order, so it is not nominal.
  • "Reputation" can be ranked (e.g., high - medium - low), so it is not nominal.
  • "Industry" is a categorical variable with no inherent order (e.g., technology, healthcare, etc.), so it is at the nominal level.
  • "Number of Employees" is a numerical variable, so it is not nominal.

Answer:

  1. Cannot be determined
  2. C. Industry
