Test the claim about the population mean, μ, at the given level of significance using the given sample statistics. Claim: μ #6000; a=0.06; o=408. Sample statistics: x=5800, n = 34 Identify the null and alternative hypotheses. Choose the correct answer below. ⒸA. Ho: μ*6000 Ho: μ#6000 Ha: μ=6000 Hg: με 6000 C. Ho: μ≤6000 Ha: μ#6000 ⒸE. Ho: μ#6000 Ha: ≤6000 Calculate the standardized test statistic. The standardized test statistic is (Round to two decimal places as needed.) B. D. Ho: H=6000 Ha: μ#6000 OF Ho: μ²6000 Ha: μ#6000 lp

Choose a process that audit analytics is used to test, which statistical sampling method would be most applicable to the process you chose?

Describe the ANOVA approach for testing differences in sample means.

Do wearable devices that monitor diet and physical activity help people lose weight? Researchers had 237 subjects, already involved in a program of diet and exercise, use wearable technology for 24 months. They measured their weight (in kilograms) before using the technology and 24 months after using the technology. (a) Explain why the proper procedure to compare the mean weight before using the wearable technology and 24 months after using the wearable technology is a matched pairs t test. Choose the correct explanation. A person's weight before and after wearing the device would not be independent; thus, the data from this before and after study should be analyzed using a matched pairs t test. O A person's weight before and after wearing the device would be independent; thus, the data from this before and after study should be analyzed using a matched pairs t test. O A person's weight before and after wearing the device would be independent; thus, the data from this before and after…

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. Your H.:µ > 9 Ha:µ < 9 а

What can researchers do to ensure their survey is valid? Why is this important? What are the different types of validity that should be considered? What other concerns may affect validity of the survey?
