Use technology to help you test the claim about the population mean, u, at the given level of significance, a, using the given sample statistics. Assume the population is normally distributed. Claim: us1160; a= 0.08; o = 198.07. Sample statistics: x = 1182.77, n = 275 %3D Identify the null and alternative hypotheses. Choose the correct answer below. O A. Ho: u> 1160 Hai HS1160 O B.

How many computers? In a simple random sample of 175 households, the sample mean number of personal computers was 2.94. Assume the population standard deviation is o =0.45. Answer the multiple choice question.

What is the null and alternative hypothesis for the following problem? Thank you

T =???

Explain the difference between statistical significance and practical significance. Choose the correct answer below. O A. Statistical significance means that the sample statistic is not likely to come from the population whose parameter is stated in the null hypothesis. Practical significance refers to whether the difference between the sample statistic and the parameter stated in the null hypothesis is large enough to be considered important in an application. O B. Statistical significance refers to how an unusual event is unlikely to actually appear in a real world application, such as every entry in a sample of size 50 having the same value. Practical significance refers to how an unusual event is likely to actually appear in a real world application, such as a rejection of a null hypothesis using data that looks feasible. O C. Statistical significance refers to the type of hypothesis test needed to analyze a population, with some tests being more important than Z tests. Practical…
