Question

A population has a mean of 5, with a standard deviation of 1. A sample of 50

items from that population has a mean of 4.5, with a standard deviation of
1.1.
Which equation describes the population parameter?
A. X = 5
OB. = 4.5
C. μ = 5
OD. X = 4.5

Answer 1

Answer:C. μ = 5

Step-by-step explanation:Option A (X = 5) and option D (X = 4.5) are incorrect because X represents a single value or observation, not a population parameter. Option B (μ = 4.5) is also incorrect because the question states that the mean of the population is 4.5, but we are looking for the equation that describes the population parameter which is the true mean of the entire population.
