QUESTION 14 A researcher, after reviewing past salary payment records, revealed that a random sample of size n with a sampling fraction of 0.125, drawn from a finite population consisting of 2000 employees, showed a sample mean salary of R19500 per month. Answer the following questions.Determine the sample total amount of money. Estimate the total amount of money paid per month. Estimate the standard error of the monthly average salary. Construct and interpret a 95% confidence interval for µ. Estimate the standard error of the monthly total salary.

A recent study found that, of the 1771 participants aged 12 to 19 in the National Health and Nutrition Examination Survey, 19.5 % had some hearing loss (defined as a loss of 15 decibels in at least one ear). This is a dramatic increase from a decade ago. The sample size is large enough to use the normal distribution, and a bootstrap distribution shows that the standard error for the proportion is SE = 0.009. Find a 99% confidence interval for the proportion of teenagers with some hearing loss. Round your answers to two decimal places. The 99% confidence interval is i to

Find a confidence interval for a. A random sample of 18 adults participated in a four-month weight loss program. Their mean weight loss was 13.4 lbs, with a standard deviation of 2.8 lbs. Use this sample data to construct a 99% confidence interval for the population mean weight loss for all adults using this four-month program. You may assume the parent population is normally distributed. Round to one decimal place. b. In the year 2000, a survey of 1158 U.S. adults were asked who they felt was the greatest President. Of those surveyed, 249 reported that Abraham Lincoln was the greatest President. Use this data to construct a 98% confidence interval for the population proportion of all U.S. adults who would say that Abraham Lincoln was the greatest president before the year 2000.
