statistics practitioner took a random sample of 48 observations from a population whose standard deviation is 23 and computed the sample mean to be 100.   Note: For each confidence interval, enter your answer in the form (LCL, UCL). You must include the parentheses and the comma between the confidence limits.   A. Estimate the population mean with 95% confidence.   Confidence Interval =  B. Estimate the population mean with 95% confidence, changing the population standard deviation to 47;   Confidence Interval =  C. Estimate the population mean with 95% confidence, changing the population standard deviation to 10;   Confidence Interval =

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.)
