Answer #1

Solution:

Which of the following descriptions of confidence intervals is correct?

Answer: c. Confidence intervals can be computed for various parameters

Explanation:

We can construct the confidence interval for various parameters like population mean, population standard deviation, population proportion, population variance, etc, Therefore, option c. Confidence intervals can be computed for various parameters is correct

    Which of the following are the characteristics of the population distribution? (Hint: 2 correct answers.) The population distribution is centered on zero. The population distribution has a standard deviation of 1. The population distribution changes depending on the sample size we use The population distribution can have a smaller standard deviation than the sampling distribution of the sample mean. The population distribution has a standard deviation of We use the population distribution when we have information only on a subsample...
