21. How does decreasing the significance level (α) affect Type I and Type II errors?

A. Decreases Type I error but increases Type II error.B. Increases both Type I and Type II errors.C. Has no effect on Type I or Type II errors.D. Decreases both Type I and Type II errors.

22. What is the formula for the test statistic when testing the mean with known population variance?

A. t = (x̄ - μ0) / (s / √n)B. z = (x̄ - μ0) / (σ / √n)C. z = (x̄ - μ0) / σD. t = (x̄ - μ0) / (σ / √n)

23. What is the formula for the test statistic when testing the mean with unknown population variance?

A. z = (x̄ - μ0) / (σ / √n)B. t = (x̄ - μ0) / (σ / √n)C. t = (x̄ - μ0) / (s / √n)D. z = (x̄ - μ0) / (s / √n)

24. What is the formula for the test statistic when testing a hypothesis about a proportion?

A. t = (p̂ - p0) / (s / √n)B. z = (p̂ - p0) / √(p̂(1-p̂)/n)C. t = (p̂ - p0) / √(p̂(1-p̂)/n)D. z = (p̂ - p0) / √(p0(1-p0)/n)

25. What is the formula for the test statistic for the difference between two means with independent samples and equal variances?

A. t = (x̄1 - x̄2) / (sp * √(1/n1 + 1/n2))B. z = (x̄1 - x̄2) / √(σ1^2/n1 + σ2^2/n2)C. t = (x̄1 - x̄2) / (sp)D. z = (x̄1 - x̄2) / (sp * √(1/n1 + 1/n2))

General5 MCQs

26. Which test is used for the difference between two means when variances are unequal?

A. Pooled t-testB. Welch's t-test (unequal variances)C. Paired t-testD. z-test

27. What are the degrees of freedom for the pooled t-test?

A. n - 1B. n1 + n2 - 1C. n1 + n2 - 2D. n1 - 1

A. (x̄1 - x̄2) / (sp * √(1/n1 + 1/n2))B. (x̄1 - x̄2) / √(s1^2/n1 + s2^2/n2)C. (p̂1 - p̂2) / √(p̂(1-p̂)(1/n1 + 1/n2))D. (d̄ - μd) / (sd / √n)

29. What is the formula for the chi-square test statistic for testing a hypothesis about variance?

A. χ^2 = (n-1)s^2 / σ0^2B. χ^2 = n s^2 / σ0^2C. χ^2 = (n-1)s / σ0D. χ^2 = (n-1)σ0^2 / s^2

30. What is the formula for the F-test statistic for testing the equality of two variances?

A. F = s1 / s2B. F = s1^2 / s2^2C. F = x̄1 / x̄2D. F = n1 / n2
