Answer #1

one sample t test is used when we want to know whether our sample comes from a particular population but we do not have full population information available to us.used when we dont know the variance.

Two sample t test

to compare the responses from two groups.these two groups can come from different experimental treatments ,or different "populations"

t? What do you further have to address if you are drawing on two samples for your test?

compares one sample mean versus another sample mean

Independent t-tests(equal samples)

Dependent t tests(dependent /paired samples)

Hypothesis Test: Difference Between Means Sample A: 20 Observations Sample B: 43 Observations My question is: Can I run an hypothesis test for the difference between means with a small sample(20) and a large sample(43)? If so, what are the steps? PS: I usually deal with exercises where the two samples have equal amount of observations.

11 . Choosing the appropriate test statistic You are interested in the difference between two population means. Both populations are normally distributed, and the population variances σ212 and σ222 are known. You use an independent samples experiment to provide the data for your study. What is the appropriate test statistic? F = √[2/n1 + 2/n2] F = s1/s2 z = (x̄1 – x̄2) / √[σ2/n1 + σ2/n2] z = (p̂1 – p̂2) / √[p̂(1 – p̂)(1/n1 + 1/n2)] Suppose instead...
