You are comparing two population means, say population A and population B. By doing that, you are calculating a 90% confidence interval for the difference means for sample A and sample B. This 90% confidence interval yields μA - μB = (-2.876, 5.398) Based on this 90% confidence interval, a student concluded that the mean of population A is more than the mean of population B.

Recall the example: We wish to know whether children who grow up without access to a smartphone have higher IQs than children in the general population. IQ is normally distributed in the general population, with μ = 100 and σ = 15 points. Suppose we draw a random sample of n = 36 children without access to a smartphone and measure each child’s IQ. The mean IQ for our sample turns out to be 103.25. Construct a 95% confidence interval....

Suppose we are sampling from a normally distributed population, and we wish to use the t procedure to find a confidence interval for the population mean. Consider the following 3 statements: I. All else being equal, the greater the sample size, the smaller the margin of error. II. All else being equal, the greater the confidence level, the greater the margin of error. III. All else being equal, the greater the sample variance, the smaller the margin of error. Which...

Suppose we determine that a study design involving the comparison of two population means is independent. We must now determine if we can use the standard Normal distribution or the Student's t distribution to compare these two population means. What exact (vital) piece(s) of information must we know to make this final decision? Be explicit in your response.
