Question

Suppose that we sample 180 diabetic patients between the ages of 50-60 in the United States. 50 of them report being diagnosed with diabetic neuropathy. Nationally, 1 out of 3 diabetics within this age group report neuropathy. What is the appropriate hypothesis test to use if we are interested in determining whether the proportion of diabetics in the sample with neuropathy is significantly different from the proportion of diabetics with neuropathy in the entire population?

Inference about a proportion (z-test)

ANOVA

Two -sample T-test

One-sample T-test

Comparison of two proportions (z-test)

Explanation / Answer

Here we need to test about the proportion and in case of proportions, we use z test.

Hence,

We will use Inference about a population (z - test).
