City A standard deviation: 20.84 thousand dollars City B standard deviation: 14.71 thousand dollars The committee wants to use the Empirical Rule to make some approximations about both data sets. Unfortunately, it is appropriate to use the Empirical Rule on only one of them! Answer the parts below to help the committee with their approximations. (a) Identify the data set for which it is appropriate to use the Empirical Rule. It is appropriate to use the Empirical Rule for the (Choose one) ▼ data set. For the data set identified in part (a), use the Empirical Rule to make the following approximations. (b) The percentage of incomes between 40.42 thousand dollars and 69.84 thousand dollars is approximately (Choose one) ▼ thousand dollars and thousand dollars. (c) Approximately 95% of the incomes are between

Hi, I'm struggling with this question and the steps on how to solve the answer

Question H: Do the results of Question F agree with Chebychev's Theorem? Explain. You can type your answer with equations and formulas for this question. (Question F attached in second photo with answer)

You wish to test the following claim (H.) at a significance level of a= 0.002. For the context of this problem, = P2-A where the first data set represents a pre-test and the second data set represents a post-test. H. = 0 You believe the population of difference scores is normally distributed, but you do not know the standard deviation You obtain pre-test and post-test samples for n = 10 subjects. The average difference (post - pre) is d -32.1 with a standard deviation of the differences of sa = 36.7.

Company A claims that their product is more consistent than the competition, Company B. We have been collecting data from Company B for many years and feel certain that Company B has a mean of μ=23.5 and a standard deviation of σ=0.43. We wish to perform an α=0.05 level test. We now collect 10 pieces of data from Company A. The mean of that data is 24.6 and the standard deviation of that data is 0.36.  What is your data value (test statistic) for this problem (3-decimal place)?  What is your chart number for this problem?

Can you please answer number 2 and all of the sub problems and show all of the steps to the solution

I need help with all parts of this question 12

question(3):  Anar scored 78 on a test that had a mean of 72 and a standard deviation of  2.7 . Omid score 66 that had a standard deviation of 1.3 (a) What is Anar Z score? (b)What is  Omid z score? (c)Which Is higher Anar or Omid?

Question 2 Save On a history test Patrick received a grade of 43 out of 50. The class mean was 35 with a standard deviation of 6. His girlfriend Kristin, in another section, received a grade of 87 out of 100. Her class mean was 75 with a standard deviation of 10. z-score for Patrick's grade (round to two decimal places) z-score for Kristin's grade = (round to two decimal places) Who received the higher grade relative to their respective classes? Why?

Hey, can you show me how to calculate part B in the attached problem?
