The data below shows the results of a survey of small business owners who have recently retired. Assume that the distribution of the population is normal. 63, 54, 69, 69, 53, 53, 71, 51, 61, 60, 69, 54 What can be concluded at the the a = 0.01 significance level What is the test statistic and the p value?Describe the ANOVA approach for testing differences in sample means.What is sample mean, sample median, sample mode, sample variance?
- Define tests of statistical significanceSuppose the total weight of passengers and luggage on an airline flight is normally distributed with mean 8914 and standard deviation 32 What is the 2.28th percentile of total passenger weightCalculate the variance of a sample for which n=5, sigmax^2=1320, sigmax=80
- A shareholders' group is lodging a protest against your company. The shareholders group claimed that the mean tenure for a chief exective office (CEO) was at least 9 years. A survey of 98 companies reported in The Wall Street Journal found a sample mean tenure of 8.7 years for CEOS with a standard deviation of s = 4.7 years (The Wall Street Journal, January 2, 2007). You don't know the population standard deviation but can assume it is normally distributed. You want to formulate and test a hypothesis that can be used to challenge the validity of the claim made by the group, at a significance level of a hypotheses are: 0.001.
