Select one: a. is evidence of bias b. is a parameter c. is a statistic d. is a sampling distribution (2): If we take increasingly larger samples from the same population, we expect Select one: a. Sampling distribution to becomes more condensed and confidence interval becomes narrower b. Sampling distribution to becomes less condensed and confidence interval becomes narrower c. Sampling distribution to becomes more condensed and confidence interval becomes wider d. Sampling distribution to becomes less condensed and confidence interval becomes wider (3) Which of the following confidence intervals has the largest critical value: 80% z-inteval or 80% t-interval with 18 degrees of freedom? WHY? (4)What is the critical value of t-distribution for an 90% confidence interval with df = 7
