In the Python script, you calculated a 95% confidence interval for the average relative skill of all teams in the league during the years of your team. Additionally, you calculated the probability that a given team in the league has a relative skill level less than that of the team that you picked.

**Probability a team has Average Relative Skill less than the Average Relative Skill(ELO) of Bulls in the years 1996 to 1998 : 0.9732
Can you please help with the 3 bullet questions above? Many thanks! :)

You have calculated the 95% confidence interval for average time in the system to be 2.00 + 1.33. The half-width of this confidence interval is?
a 95% confidence interval for the average number of cavities a person has in their lifetime is given by (2.4,5.3). Which of the following is an appropriate interpretation of the CONFIDENCE LEVEL in this example? Group of answer choices: 95% of all people have between 2.4 cavities and 5.3 cavities in their lifetime. There is a 95% change (probability) that this interval correctly estimates the true average number of cavities a person will have in their lifetime. A person has...
A 95% confidence interval for a population mean was calculated. The sample mean was found to be 34.5 and the MOE was found to be 4.06 giving us a confidence interval of 34.5±4.06 or equivalently written as 30.44 to 38.56. (a) For the hypotheses H0:?=30 Ha:??30, would you reject the null hypothesis at the 5% level of significance (i.e. ? = 0.5)? (Type: YES or NO or CANNOT TELL): (b) For the hypotheses H0:?=41 Ha:??41, would you reject the null...
3. A report stated that the 95% confidence interval for the average gas mileage in miles based on 49 SUVS is (18, 22). The report also stated that the confidence interval was calculated assuming the population standard deviation was known, but it did not state the value. 1. What is the population standard deviation? 2. Can you conclude that mileage is greater than 17 miles at 1% significance?
You construct a 95% confidence interval for a population mean using a random sample. The confidence interval is 24.9 less thanmuless than31.5. Is the probability that mu is in this interval 0.95? Explain.
Suppose you construct a 95% confidence interval estimate of the true population mean by conducting a random sample of size n=100. Your sample mean x (with a bar over it) = 80.5 and your calculated maximum error of the estimate is E = 3.5. What does this suggest? Circle answer. a. in 5% of all samples of this size, the mean is more than 84, b. in 95% of all samples of this size, the mean is at least 77,...
Assume we have taken an SRS of 49 UCLA students and calculated a 95% confidence interval for the mean age to be 23 < µ< 27 years. Determine which of the following interpretations are True. Then answer parts i and ii in the space below. A. A 95% confidence interval for the mean age of students at UCLA is 23 to 27. This means that 95% of all students are in this interval. B. A 95% confidence interval for the mean...
What would happen (other things being equal) to a confidence interval if you calculated a 99% confidence interval rather than a 95% confidence interval? Question 11 options: It will not change. It will be wider. It will be narrower.
Suppose you are told that a 95% confidence interval for the average price of a gallon of regular gasoline in your state is from $2.93 to $4.21. Use the fact that the confidence interval for the mean is in the form x − E to x + E to compute the sample mean and the maximal margin of error E. (Round your answers to two decimal places.) x = $ E = $
Suppose you are told that a 95% confidence interval for the average price of a gallon of regular gasoline in your state is from $2.91 to $4.40. Use the fact that the confidence interval for the mean is in the form x − E to x + E to compute the sample mean and the maximal margin of error E. (Round your answers to two decimal places.) x = $ E = $
