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

Can you help me determine the P value for the following equation? I received 0.528 (rounded 3 decimal places) for my answer but it stated that it was incorrect. I utilized the Ti-84 calculator for my answer.

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

The salaries paid to the managers of a company had a mean of dollar 20,000 with a standard deviation of Dollar 3,000. What will be the mean and standard deviation if all the salaries are increased by (i) 10%, (ii) 10% of the existing mean? Which policy would you recommend if the management does not want to have increased disparities in waves ?

Date: 9/3/2021 t: Engineering Statistics Q1 (Answer only two questions) (a) Find the mean, median, mode, range and coefficient of variation for the following data (standard deviation = 152.971). 420 360 180 240 300 180 60 540 Q1-(b) Draw the histogram and frequency polygon for the frequency distribution table below,

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
