Question

question 4 (1 point)
each set of data was collected from surveys to answer statistical questions. select all of the data sets that represent numerical data.

a {a, a, a, b, b, b, c, c, c}
b {-7, -5, -3, -1, -1, -1, 0}
c {1, 1.2, 1.4, 1.4, 1.5, 1.6, 1.8, 1.9, 2, 2, 2.1, 2.5}
d {45, 60, 60, 70, 75, 80, 85, 90, 90, 100, 100, 100}
e {98.2, 98.4, 98.4, 98.6, 98.6, 98.6, 98.6, 98.7, 98.8, 98.8}
f {red, red, yellow, yellow, blue, blue, blue}
g {yes, yes, yes, yes, maybe, maybe, no, no, no}

Explanation:

Numerical data consists of numbers (either integers, decimals, etc.) that can be used for mathematical operations or statistical analysis. Let's analyze each option:

• Option a: Contains letters (A, B, C) which are categorical, not numerical.
• Option b: Contains integers and a zero, all numerical values.
• Option c: Contains decimals and integers, all numerical values.
• Option d: Contains integers, all numerical values.
• Option e: Contains decimals, all numerical values.
• Option f: Contains color names (categorical), not numerical.
• Option g: Contains text responses (Yes, Maybe, No - categorical), not numerical.

Answer:

b. \{-7, -5, -3, -1, -1, -1, 0\}, c. \{1, 1.2, 1.4, 1.4, 1.5, 1.6, 1.8, 1.9, 2, 2, 2.1, 2.5\}, d. \{45, 60, 60, 70, 75, 80, 85, 90, 90, 100, 100, 100\}, e. \{98.2, 98.4, 98.4, 98.6, 98.6, 98.6, 98.6, 98.7, 98.8, 98.8\}
