Gestation Periods of Humans. For humans, gestation periods are normally distributed with a mean of 266 days and a standard deviation of 16 days. Suppose that you observe the gestation periods for a sample of nine humans. a. Theoretically, what are the mean and standard deviation of all possible sample means? b. Use the technology of your choice to simulate 2000 samples of nine human gestation periods each. c. Determine the mean of each of the 2000 samples you obtained in part (b). d. Roughly what would you expect the mean and standard deviation of the 2000 sample means you obtained in part (c) to be? Explain your answers. e. Determine the mean and standard deviation of the 2000 sample means you obtained in part (c). f. Compare your answers in parts (d) and (e). Why are they different?
9. Determines the average, median and standard deviation of each of the distributions to a variable (age, girl reaction time and boys reaction time).What interpretations can you make of it? B.) For each of the three two-variable distributions, make a graphical representation using a technological tool and calculate the values that can be used to interpret them. C.) Interpret graphic representations and draw conclusions.
9) A small value of the mean of a data set indicates that the values of that data set are spread over a relatively smaller range around the standard deviation. Select one: False True
A marketing executive is investigating whether this year’s advertising campaign has resulted in greater mean sales compared with last year’s mean sales. The executive collects a random sample of 100 customer orders from a large population of orders and calculates the sample mean and sample standard deviation. Which of the following is the appropriate test for the executive’s investigation? a)A one-sample z-test for a population mean b)A one-sample t-test for a population mean c)A one-sample z-test for a population proportion d)A two-sample t-test for a difference between means e)A matched-pairs t-test for a mean difference
Consider the following population data; 0, -4, 2, -8, 10 a) Calculate the population variance. b) Calculate the population standard deviation
Consider two populations of students. Both populations are the same size (1000). The first population consists of all students at a grade school (grades 1-5). The second population consists of all students at a middle school (grades 6-8). Which school's population is more likely to have a larger standard deviation in the age of its students? a) The grade school's population is more likely to have the larger standard deviation. b) The middle school's population is more likely to have the larger standard deviation. c) They would most likely have the same standard deviation for age. a) It is impossible to say without more information.
The ages of the winners of a cycling tournament are approximately bell-shaped. The mean age is 27.1 years, with a standard deviation of 3.2 years. The winner in one recent year was 22 years old. (a) Transform the age to a z-score. (b) Interpret the results. (c) Determine whether the age is unusual. C....) (a) Transform the age to a z-score. %= (Type an integer or decimal rounded to two decimal places as needed.)
