Determine Normality of Single Observation with Z-Test

Q: Determine Normality of Single Observation with Z-Test

This question evaluates understanding of hypothesis testing fundamentals, specifically the ability to formulate null and alternative hypotheses and specify a decision rule for a single observation against a fully specified reference distribution.

Question

Hypothesis Test for a Single Observation Against a Standard Normal

Context

You observe a single numeric value, x, and want to decide whether it could plausibly have been drawn from a standard normal distribution N(0, 1). Assume the reference distribution (mean = 0, variance = 1) is fully specified and not estimated from data.

Question

Which statistical test would you use?
State the null and alternative hypotheses.
Give the decision rule at a chosen significance level α.
