Answer to Problem 80E
Mean is 305.86.
Explanation of Solution
Given:
Calculation:
The mean for the 7 defensive linemen is given below:
The mean tells us how large each observation in the data set would be if the total were split equally among all the observations i.e. mean is a "fair share" or a balance point. From this have noticed that there are 3 observations below mean and 4 observations above mean. If we leave out the smallest (285) observation the mean would be 309.33 which is the balance point of the data. One observation brings down the value of mean by 3.47 points. Now with 309.33 mean of six observations (after leaving the extreme observation) three observations are above and three observations are below 309.33.
Conclusion: “Thus, we conclude that due to presence of extreme value mean gets affected. Mean is sensitive to outliers.”

- Can you help me solve problem 38 with steps im stuck.arrow_forwardHow do the samples hold up to the efficiency test? What percentages of the samples pass or fail the test? What would be the likelihood of having the following specific number of efficiency test failures in the next 300 processors tested? 1 failures, 5 failures, 10 failures and 20 failures.arrow_forwardThe 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_forward
