Question
Chapter 6, Problem 1CS
To determine
To explain: The phrase “statistically significant.”
Expert Solution & Answer
Answer to Problem 1CS
Solution: The “statistically significant” can be interpreted as there is strong indication that the withdrawal symptoms can occur too frequently just by chance when the subjects get the capsules that do not contain caffeine.
Explanation of Solution
The statistically significant result indicates that there is a strong signal that the results can occur too frequently just by chance.
In the provided study, a number of subjects displayed withdrawal symptoms when they got the capsules that did not contain caffeine. The amount of the symptoms was measured as statistically significant. Here, “statistically significant” can be explained as there is a strong evidence that the withdrawal symptoms can occur too frequently just by chance when the subjects get the capsules that do not contain caffeine.

- The battery temperatures are a major concern for us. Can you analyze and describe the sample data? What are the average and median temperatures? How much variability is there in the temperatures? Is there anything that stands out? Our engineers’ assumption is that the temperature data is normally distributed. If that is the case, what would be the likelihood that the Safety Zone temperature will exceed 5.15 degrees? What is the probability that the Safety Zone temperature will be less than 4.65 degrees? What is the actual percentage of samples that exceed 5.25 degrees or are less than 4.75 degrees? Is the manufacturing process producing units with stable Safety Zone temperatures? Can you check if there are any apparent changes in the temperature pattern? Are there any outliers? A closer look at the Z-scores should help you in this regard.arrow_forwardNeed help pleasearrow_forwardPlease conduct a step by step of these statistical tests on separate sheets of Microsoft Excel.
