Question 4 To test the hypothesis that the population mean mu-7.0, a sample size n=27 yields a sample mean 7.031 and sample standard deviation 0.445. Calculate the P-value and choose the correct conclusion. Your answer: The P-value 0.209 is not significant O and so does not strongly suggest that mu>7.0. The P-value 0.209 is significant and so strongly suggests that mu>7.0. The P-value 0.360 is not significant O and so does not strongly suggest that mu>7.0. The P-value 0.360 is significant and so strongly suggests that mu>7.0. The P-value 0.017 is not significant O and so does not strongly suggest that mu>7.0. The P-value 0.017 is significant and so strongly suggests that mu>7.0. The P-value 0.383 is not significant O and so does not strongly suggest that mu>7.0. The P-value 0.383 is significant and so strongly suggests that mu>7.0. The P-value 0.308 is not significant O and so does not strongly suggest that mu>7.0. The P-value 0.308 is significant and so strongly suggests that mu>7.0.…

Amy noted the prices ($) of a random sample of n=9 items to be used by her in a project as: X1=87, x2 67, x3= 15, x4=20, x5 = 34, x6=54, x7=22, Xg 95, and xg=20. Find the maximum value. (Do not type $ or dollars in your answer). QUESTION 4 Question 17, Given a sample of n=5 data values: X1 = 12, x2= 23, x3=26, x4=28, and x5 =10 Up to three decimal places, find the following:
Question 1 A random sample of 101 recorded deaths in the United States during the past year showed an average life span of 71.8 years. Assuming a sample standard deviation of 8.9 years, does this seem to indicate that the population variance is more than 64 squared years? Use a 0.05 level of significance. Answers that use CIs will not be accepted. Formulate and carry out the appropriate hypothesis test using the critical region approach.
The composite ACT scores for Idaho students who took the test in 2019 have average 22.3 with the standard deviation 2.25 and approximately normal distributed. In a random sample of 49 students who took the exam in 2019, the average composite ACT score is 23.5 with standard deviation 1.06. (show your work) Which one is true? 3 and 2.25 are statistics, and 1.06 are parameters. 3 and 2.25 are parameters, and 1.06 are statistics. All numbers 22.3, 2.25 and 23.5, 1.06 are parameters. All numbers 22.3, 2.25 and 23.5, 1.06 are statistics. What is the probability that the score is 23 or more if we random select one student? Find the 85th percentile the composite ACT scores for Idaho students
Question4: The times for untrained rats to run a standard maze has a normal distribution where the times are measured in seconds. The researcher hopes to show that training improves the times. A sample of 9 rats were selected and the time to run a standard maze before and after training were measured in seconds and shown below. Does the data support the researcher’s hypothesis? Conduct a hypothesis test at 5% significant level (specify 4 steps).
QUESTION 15 A minimum mileage guarantee on the tires of a tire manufacturing company is being considered to be set. When the cormpany conducted many tire tests, it revealed that the mean miksage has a normal distribution with mean 4,743 and standard deviation 60 The tire manufacturer wants to set the minimum guaranteed mileage so that no more than 2.5 percent of tires will have to be exchanged. Calculate the Lower limit of guaranteed mikeage? (Round answer to lwo decimal places ex. 2.09)
