State the decision rule in terms of the critical value of the test statistic. b. State the calculated value of the test statistic. c. State the conclusion.
Assume that you are conducting a test with the following hypothesis Ho: μ = 11 vs Ha: μ < 11. The test statistic for the test is t = -2.96 with a sample size of 30. What is the p-value for this test? Select one: a. between 0.100 and 0.050. b. between 0.05 and 0.025 c. between 0.005 and 0.01 d. between 0.0025 and 0.005 e. between 0.02 and 0.01

Question 4 (6 marks) Part a) Calculate the statistic, set up the rejection region, interpret the result, and draw the sampling distribution. Ho: Hi: μ 10 μ#10 Given that: σ-10, n-100, X-10, α-0.05. Part b) A statistics practitioner is in the process of testing to determine whether is enough evidence to infer that the population mean is different from 180. She calculated the mean and standard deviation of a sample of 200 observations as X -175 and s-22. Calculate the...
PLEASE HELP AND SHOW WORK.... AMD IF THERE IS A CALCULATOR WAY PLEASE SHOW IT ON TI84. You wish to test the following claim (Ha) at a significance level of α-0.02 Ho: μ = 52.4 52.4 Ha: μ You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size n 20 with mean M 55.8 and a standard deviation of SD 6.3. What is the p-value for this sample? (Report...

Please help me get the right values, I cannot figure it out. Please show your work. A statistical program is recommended The following observations are on stopping distance (ft) of a particular truck at 20 mph under specified experimental conditions 32.1 30.8 31.7 30.4 31.0 31.9 The report states that under these conditions, the maximum alowable stopping distance is 30. A normal probability plot validates the assumption that stopping distance is normally distributecd. (a) Does the data suggest that true...
