Question

Two independent samples of sizes 13 and 24 are randomly selected from two normal populations with variances s12=214 and s22=235, respectively. Which of the following distributions should be used for developing confidence intervals about the difference between the two population means (μ1 - μ2)?

Answer 1

We can use the normal distribution to develop confidence intervals about the difference between the two population means (μ1 - μ2).

Step-by-step explanation:

In this question, we are interested in developing confidence intervals about the difference between the two population means (μ1 - μ2).

Since the population variances are known for each sample, we can use the normal distribution to develop confidence intervals.
