You want to estimate the mean amount of time Internet users spend on Facebook each month. How many Internet users must be surveyed in order to be 90% confident that your sample mean is within 10 minutes of the population mean? Based on results from a prior survey, assume that the standard deviation of the population of monthly times spent on Facebook is 210 minutes.
A developmental psychologist is interested in studying how long babies gaze at a photograph of a human face. To test this question, she shows a picture to a sample of six babies and records the length of their gaze in seconds. The data are as follows: 12, 17, 18, 20, 20, 29. Calculate the mean, median, mode, range, variance and standard deviation for the sample.
when computing descriptive statistics, we are interested only both describing our data and also in presenting the means and standard deviations of all dependent variables. True or false When writing your participant section, you include all measures of central tendency (mean, median, mode) and all measures of variablility (variance, range, standard deviation). True or false
You may need to use the appropriate appendix table or technology to answer this question. In order to estimate the difference between the average yearly salaries of top managers in private and governmental organizations, the following information was gathered. Sample Size Sample Mean (in $1,000s) Sample Standard Deviation (in $1,000s) ** Note $ Private 45 92 8 Governmental 53 82 9 Develop an interval estimate for the difference between the average yearly salaries of top managers of the two sectors. Use 95% confidence and give your answers in dollars. Use technology to find the critical value when df = 95. (Use Private Governmental. Round your answers to the nearest whole dollar.) the data table represents 1000's so be sure to answer the question in 1000's. Example: If the low bound is 7.365, the actual amount in thousands is 7365. to $
z Scores LeBron James, one of the most successful basketball players of all time, has a height of 6 feet 8 inches, or 203 cm. Based on statistics from Data Set 1 “Body Data” in Appendix B, his height converts to the z score of 4.07. How many standard deviations is his height above the mean?
What was the age distribution of prehistoric Native Americans? Extensive anthropological studies in the southwestern United States gave the following information about a prehistoric extended family group of 84 members on what is now a Native American reservation. For this community, estimate the mean age expressed in years, the sample variance, and the sample standard deviation. For the ciass 31 and over, use 35.5 as the class midpoint. (Round your answers to one decimal place.) Age range (years) Number of individuals 1-10 11-20 19 21-30 15 31 and over 40 10
The ages of undergraduate students at two universities (one in the east and one in the west) are being compared. Researchers want to know if there is a difference in the mean age of students at the two universities. The population standard deviations are known. The following data shows the results of samples collected at each institution: School Location n (sample size) sample mean ( ) population standard deviation West 33 25.78 6.29 East 35 23.16 7.52 What is the value of the test statistic for the previous problem? (Enter your answer as a positive value even if you calculated a negative test statistic value i.e. if you calculated -1.311 you should enter 1.311). Round your answer to 3 decimal places.
