Conditions of Significance Tests for Proportions

March 24, 2021

Random Condition

• The data come from a random sample from the population of interest.

• This is the same from Confidence Intervals

• Random Condition never changes!

Large Counts

• : Both np₀ and n(1 − p₀) are at least 10.

• p₀ = null value = original value

• This is similar to confidence intervals, but now we use the null value instead of the sample proportion

Multiple Choice

What is the random condition for Significance Tests of Proportions?

• The data comes from a random sample.

• np₀ ≥ 10 and n(1-p₀) ≥ 10

• n ≥ 30

• The data is independent.
