Solve A and B! You need to always show that conditions are met for any test or confidence interval and these questions are from a population that we do not know the population parameters, z tests cannot be performed.Do not use z tests on this question!!! 1. Some people believe that math ability and musical ability have a relationship -that is, people with musical ability also seem to do well in math. A group ofresearchers decides to test this theory. The researchers randomly select 100musically gifted individuals and also 150 individuals with no musical talent.Each individual is given a test for math ability. The results are shown below:Musically Gifted Not Musically Giftedx = 90.6x = 88.4S = 1.8S = 2.6n = 100n = 150A. Run an appropriate test to see if the mean math-ability score for those whoare musically gifted is significantly higher than that of those who are notmusically gifted. Use a 1% level of significance.Let u₁ = mean math-ability score for those who are musically giftedLet u = mean math-ability score for those who are not musically gifted B. Find and interpret a 90% confidence interval for u-u. Provide aconclusion pertaining to hypothesis.

Question one is complete. I am looking for help with question two. I need to explain what these results mean- not necessarily just showing the work like I did with part one. I had this question answered but they just did the math, which I didn't understand nor could I then explain what the results of that math meant. Like what can my boss do with this information. ***DONE***1.) Construct a 95% Confidence Interval with a known population standard deviation of 26.29. Briefly explain to your boss the results of your C.I. Calculation. Your boss is still not completely convinced that the project was a success, so she asks you to: 2.) Go through the 5 step one-sample hypothesis testing procedure to determine if the sample mean is different than the pre-improvement project population mean of 497.21, using an alpha = .05 (this is a two tailed test). Explain the results to your boss. Sample Waste Pounds (Table #2) 469 485 468 463 472 480…
There are many products that on their label, establish a content of the packaging. Select a brand of cleaning detergent (for example ACE or Tide). In their label, they establish a weight of the amount of detergent in each box. Choose a sample of 8 boxes from the selected company and weight the 8 samples on a scale. Collect this information and build a hypothesis test, a confidence interval, a P – value and size of sample (n) by comparing the average weight of the samples with the one on the box label. It determines, through the hypothesis test, if there is any difference in the average weight of the sample boxes with the one that appears in the box. Use an alpha for this 0.01 test. What is your conclusion?
Choosing the alpha level for a hypothesis test allows researchers to control the probability of committing a type II error. True or False I see various answers on this question Please explain.
23) It is found that a 95% confidence interval for the mean score of all students on an aptitude test is (62, 70). It means that there is a 95% chance that the mean score of all students on an aptitude test is between 62 and 70. False True
If the distribution of the population has a nonzero standard deviation and mean 12 then the probability that an individual data value will be greater than 14 is always less than the probability that the mean of 45 randomly selected data values will be greater than 14. True or False
"Power is higher with a one-tailed test than with a two-tailed test as long as the hypothesized direction is correct" Explain this statement?
Say we have a population parameter, and the 95% confidence interval for it is (-3, 10). Do you have evidence to conclude that the parameter is less than 11? Yes No
A local chess club claims that the length of time to play a game has a standard deviation of less than 11 minutes. Write sentences describing type I and type Il errors for a hypothesis test of this claim. A type I error will occur if the actual standard deviation of the length of time to play a game is V 11 minutes, but you the null hypothesis, A type Il error will occur if the actual standard deviation of the length of time to play a game is 11 minutes, but you the null hypothesis,
