Suppose a 90% confidence interval estimate mean is (25.2, 43.4). Now, using the same exact information, you compute a 95% confidence interval. Which of the following statements is correct? O The 95% confidence interval is longer. The answer can't be determined from the information given. The intervals have the same lengths The 95% confidence interval is shorter
Gonstruct a 90% confidence interval for the population mean. The 90% confidence interval is (____, ____). (Round to two decimal places as needed.) Construct a 95% confidence interval for the population mean The 95% confidence interval is (____, ____). (Round to two decimal places as needed.) Interpret the results. Choose the correct answer below. A. With 90% confidence. it can be said that the population mean price lies in the first interval. With 95% confidence, it can be said that the population mean price lies in the second interval. The 95% confidence interval is narrower than the on% B. With 90% confidence. it can be said that the population mean price lies in the first interval. With 95% confidence, it can be said that the population mean price lies in the second interval. The 95% confidence interval is wider than the 90% C. With 90% confidence, it can be said that the sample mean price lies in the first interval. With 95% confidence, it can be said that the sample mean price…
A survey asked, "How many tattoos do you currently have on your body?" Of the 1241 males surveyed, 182 responded that they had at least one tattoo. Of the 1047 females surveyed, 139 responded that they had at least one tattoo. Construct a 99% confidence interval to judge whether the proportion of males that have at least one tattoo differs significantly from the proportion of females that have at least one tattoo. Interpret the interval. P1 Let p, represent the proportion of males with tattoos and p, represent the proportion of females with tattoos. Find the 99% confidence interval for p, - p2. The lower bound is The upper bound is (Round to three decimal places as needed.)
Use the formula in this example to determine the sample size, n.The estimated prevalence is 19%, and the desired confidence level is 93% with a margin of error of 4%. (Round your answer to the nearest integer.)n =

A survey asked, "How many tattoos do you currently have on your body?" Of the 1233 males surveyed, 183 responded that they had at least one tattoo. Of the 1042 females surveyed, 139 responded that they had at least one tattoo. Construct a 95% confidence interval to judge whether the proportion of males that have at least one tattoo differs significantly from the proportion of females that have at least one tattoo. Interpret the interval. C Let p₁ represent the proportion of males with tattoos and p2 represent the proportion of females with tattoos. Find the 95% confidence interval for p₁ -P2- The lower bound is The upper bound is (Round to three decimal places as needed.)
