Question

what kind of hypotheisis test is this?
1 population proportion
2 population proportions
2 population means
1 population mean

Explanation:

To determine the type of hypothesis test, we analyze the options. A 1 - population proportion test is used when we want to test a claim about the proportion of a single population (e.g., the proportion of voters who support a candidate in one city). A 2 - population proportions test is for comparing proportions of two populations. A 2 - population means test is for comparing means of two populations, and a 1 - population mean test is for testing a claim about the mean of one population. Since the question is about identifying the type, and if we assume the context is about a single population's proportion (e.g., testing if the proportion of defective items in a single production line is a certain value), the "1 population proportion" test is the relevant one among the options for a single - population proportion - related hypothesis test.

Answer:

1 population proportion
