Answer #1

p = 5/50 = 0.1

n = 50

Z for 98% confidence interval = Z0.01 = 2.33

Confidence interval

                               

                               

                                = (0.001 , 0.199)

Kathy sets out wanting to find a 98% confidence interval for a population mean; however, she later decides that she wants to know the 95% confidence interval for that same population mean. How will this affect the width and the margin of error of her confidence interval for a population mean? Assume that the population standard deviation is unknown and the population distribution is approximately normal.

Construct the 98 % confidence interval for the difference −μ1μ2 when =x1475.12 ,   =x2321.34 ,   =s143.48 ,   =s221.60 ,   =n112 , and =n215 . Use tables to find the critical value and round the answers to at least two decimal places. A 98 % confidence interval for the difference in the population means is <<−μ1μ2 .

Suppose we construct a 98% confidence interval for the mean. The interval ranges from [1100, 1200]. The 98% confidence interval for the population mean can be interpreted as follows: If all possible samples are taken and confidence intervals are calculated, 98% of those intervals would include the true population mean somewhere in their interval. One can be 98% confident that you have selected a sample whose range does not include the population mean. One can be 98% confident that the...
