An outbreak of the deadly Ebola virus in 2002 and 2003 killed 91 of the 95 gorillas in 7 home ranges in the Congo. To study the spread of the virus, measure " distance" by the number of home ranges separating a group of gorillas from the first group infected. Here are data on distance and number of days until deaths began in each later group: Use a calculator or software to find the following values. (a) Find the mean and standard deviation of . MEAN: STANDARD DEVIATION: (b) Find the mean and standard deviation of y. MEAN: STANDARD DEVIATION: (c) Find the correlation between and y r Distance Days y E 445 347 418 304148 48

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.

A company conducted a survey to determine the average age of its employees. The ages of 10 randomly selected employees are as follows: 25, 28, 30, 35, 40, 42, 45, 48, 50, and 55. Calculate the sample mean, sample variance, and standard deviation of the ages.
