Please someone help me! I've been stuck on this for two weeks and need help ASAP!! Please don't give me any links or spam. I will give Brainlist to whoever actually does this! Show all math performed (label the calculation or give the formula, show your setup, and give the result) and include proper labels. Also, answer any questions asked in the lab.
1. In tossing one coin 10 times, what are your chances for tossing a head? a tail?

2. In tossing one coin 100 times, what are your chances for tossing a head? a tail?

3. In tossing one coin 200 times, what are your chances for tossing a head? a tail?

deviation = ((absolute value of the difference between expected heads and observed heads) + (absolute value of the difference between expected tails and observed tails)) divided by total number of tosses. This value should always be positive.
4. What is the deviation for 10 tosses?

5. What is the deviation for the 100 tosses?

6. What is the deviation for 200 tosses?

7. How does increasing the total number of coin tosses from 10 to 100 affect the deviation?

8. How does increasing the total number of tosses from 100 to 200 affect the deviation?

9. What two important probability principles were established in this exercise?

10. The percent of occurrence is the obtained results divided by the total tosses and multiplied by 100%. Toss the coins 100 times and record your results.

Jobs and productivity! how do retail stores rate? one way to answer this question is to examine annual profits per employee. the following data give annual profits per employee (in units of 1 thousand dollars per employee) for companies in retail sales. assume σ ≈ 4.0 thousand dollars. 3.7 6.7 3.6 8.5 7.5 5.9 8.7 6.4 2.6 2.9 8.1 −1.9 11.9 8.2 6.4 4.7 5.5 4.8 3.0 4.3 −6.0 1.5 2.9 4.8 −1.7 9.4 5.5 5.8 4.7 6.2 15.0 4.1 3.7 5.1 4.2 (a) use a calculator or appropriate computer software to find x for the preceding data. (round your answer to two decimal places.) thousand dollars per employee (b) let us say that the preceding data are representative of the entire sector of retail sales companies. find an 80% confidence interval for μ, the average annual profit per employee for retail sales. (round your answers to two decimal places.) lower limit -- thousand dollars upper limit -- thousand dollars (c) let us say that you are the manager of a retail store with a large number of employees. suppose the annual profits are less than 3 thousand dollars per employee. do you think this might be low compared with other retail stores? explain by referring to the confidence interval you computed in part (b). yes. this confidence interval suggests that the profits per employee are less than those of other retail stores. no. this confidence interval suggests that the profits per employee do not differ from those of other retail stores. correct: your answer is correct. (d) suppose the annual profits are more than 6.5 thousand dollars per employee. as store manager, would you feel somewhat better? explain by referring to the confidence interval you computed in part (b). yes. this confidence interval suggests that the profits per employee are greater than those of other retail stores. no. this confidence interval suggests that the profits per employee do not differ from those of other retail stores. (e) find an 95% confidence interval for μ, the average annual profit per employee for retail sales. (round your answers to two decimal places.) lower limit 3.75 incorrect: your answer is incorrect. thousand dollars upper limit 6.41 incorrect: your answer is incorrect. thousand dollars
