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.

Calculate the variance for the following dataset:  15 17 17 5 5

Suppose that warranty records for a car maker show that the probability that a new car needs a warranty repair in the first 90 days is 20%. If a random sample of 20 new cars is selected, what is the probability that more than 6 will need a warranty repair? 0.0321 0.9133 0.0867 0.1091

A researcher wants to know if there is a difference between the mean amount of sleep that people get for various types of employment status. The table below shows data that was collected from a survey. Unemployed Part Time Worker Full Time Worker 9 7 7 9 9 5 7 7 7 7 8 8 9 6 7 10 7 8 10 9 5 8 8 8 9     Assume that all distributions are normal, the three population standard deviations are all the same, and the data was collected independently and randomly. Use a level of significance of α=0.1α=0.1.H0: μ1=μ2=μ3H0: μ1=μ2=μ3Ha:Ha: At least two of the means differ from each other. For this study, we should use              The test-statistic for this data =  (Please show your answer to 4 decimal places.) The p-value for this sample =  (Please show your answer to 4 decimal places.)
