A newspaper reported that the mean annual household income of its readers is GHC119,155. Assume this estimate of the mean annual household income is based on a sample of 80 households, and based on past studies, the population standard deviation is known to be o = GHC30,000. Develop a 95% confidence interval estimate of the population mean.

The length of students' college careers at Anytown University is known to be normally distributed, with a mean length of 5.5 years and a standard deviation of 1.75 years. What is the lower quartile for the length of students' careers at Anytown University?
The common fruit fly Drosophila melanogaster is the most studied organism in genetic research because it is small, is easy to grow, and reproduces rapidly. The length of the thorax (where the wings and legs attach) in a population of male fruit flies is approximately Normal with mean 0.800 millimeters (mm) and standard deviation 0.078 mm. Use software or Table A. (a) What proportion of flies have thorax length less than 0.66 mm? (Enter your answer as a percentage rounded to two decimal places.) 6.18 proportion: Incorrect (b) What proportion of flies have thorax length greater than 0.93 mm? (Enter your answer as a percentage rounded to two decimal places.) 18.41 proportion: Incorrect
Assume that a certain data is approximately bell-shaped with mean 91 and standard deviation 6. Use the Empirical Rule to find the percent of the data between 85 and 103. Show all the necessary calculations.
A trial study suggest that the standard deviation for the half life for the drug chlordiazepoxide is 8 hours. With 99% confidence, find the sample size needed to determine the mean half life for the drug with a margin of error of 3 hours.
A blood bank is conducting a study on how much time is required of their patients for blood platelet donations. Based on past records, time spent in the waiting room has a mean of 5 minutes and a standard deviation of 1 minute, time spent with a nurse who reviews patients' medical records and measures their vital signs has a mean of 10 minutes and a standard deviation of 3 minutes, and the actual donation time has a mean of 130 minutes and a standard deviation of 8 minutes. Assuming these three times are independent and can all be modeled using a normal distribution, approximately what proportion of donors finish the entire donation process in under 2.5 hours (150 minutes)? (A) 0.66 (B) 0.72 (C) 0.84 (D) 0.89 (E) 0.99
The ages of a group of 138 randomly selected adult females have a standard deviation of 17.5 years. Assume that the ages of female statistics students have less variation than ages of females in the general population, so leto= 17.5 years for the sample size calculation. How many female statistics student ages must be obtained in order to estimate the mean age of all female statistics students? Assume that we want 95% confidence that the sample mean is within one-half year of the population mean. Does it seem reasonable to assume that the ages of female statistics students have less variation than ages of females in the general population? The required sample size is (Round up to the nearest whole number as needed.)
A random survey of 75 death row inmates revealed that the mean length of time on death row is 17.1 years with a standard deviation of 6.5 years. Conduct a hypothesis test to determine if the population mean time on death row could likely be 15 years or not.
Suppose that shoe sizes of American women have a bell-shaped distribution with a mean of 8.068.06 and a standard deviation of 1.521.52. Using the empirical rule, what percentage of American women have shoe sizes that are at least 9.589.58?

The combined SAT scores for the students at a local high school are normally distributed with a mean of 1478 and a standard deviation of 292. The local college includes a minimum score of 689.6 in its admission requirements.What percentage of students from this school earn scores that satisfy the admission requirement?
A study showed that two years ago, the mean time spent per visit to Facebook was 20.1 minutes. Assume the standard deviation is 7 minutes. Suppose that a simple random sample of 103 visits was selected this year and has a sample mean of 22.1 minutes. A social scientist is interested to know whether the mean time of Facebook visits has changed. Use the a=0.05 level of significance and the p-value method with the table.
