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 following conditions must meet:
1. The information is an easy 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 is the sample size and P is that the true proportion of the population.
