Question

What conditions must be met to test a hypothesis about a
population proportion?

What test statistic would we use when comparing two population
proportions?

What test statistic would we use when comparing observed vs.
expected frequencies?

If my degrees of freedom were 7 and I am comparing observed
and expected frequencies at a 0.01 level of significance. What
would my critical value be?

Answer #1

**Answer:**

**Question 1**

When conducting a hypothetical test of one population, the
subsequent characteristics must be present:

1. The information is a straightforward random sample of the
population of interest

2. The population is a minimum of 10 times larger than the
sample.

3. n⋅p≥10 and n⋅ (1−p) ≥10, Where N The sample size is and P is
that the true proportion of the population.

(Note: “Since you have asked multiple questions, we will solve the first question for you. If you want any specific question to be solved then please specify the question number or post only that question.” )
