Where,As the level of confidence (C) increases, which increases the z-critical value, Hence the margin of error increases which in turn widens the width of the confidence interval. Since the sample size is inversely proportional to the margin of error, As the sample size increase, the margin of error will narrow which in turn narrows the width of the confidence interval. Since the population standard deviation is directly proportional to the margin of error, As the standard deviation increases, the margin of error increases, which in turn widens the width of the confidence interval.

na test of the effectiveness of garlic for lowering cholesterol, 47 subjects were treated with garlic in a processed tablet form. Cholesterol levels were measured before and after the treatment. The changes (before - after) in their levels of LDL cholesterol (in mg/dL) have a mean of 3.4 and a standard deviation of 19.8. Construct a 95% confidence interval estimate of the mean net change in LDL cholesterol after the garlic treatment. What does the confidence interval suggest about the effectiveness of garlic in reducing LDL cholesterol? Click here to view a t distribution table.

Step 2 (b) Which of the two intervals conveys more precise information about the value of the population proportion? Recall that a smaller standard error of results in a narrower confidence interval. A narrower confidence interval is then more precise. The width of Interval 1, (0.27, 0.35), is 0.35 0.27 = and the width of Interval 2, (0.30, 0.34), is 0.34 -0.30 = Submit Skip (you cannot come back) Therefore, --Select--- is the narrower and more precise interval.
