Question

A. Consider the population of integers from 1 to 1000 whose = 500.5 with sigma unknown:

  1. Solve for the sample mean and SD of the random sample below:

169            59        989      608

897            368      769      996

635            482      692      915

611            88        916      66

26              608      69        532

 

  1. What is the mean of the sampling distribution of means?
  2. Which distribution is more appropriate to use: Z or t? Why?
  3. Solve for SE. Use the correct statistical symbol.
  4. Graph the sampling distribution of means. Label the mean values up to +0 from the center.
  5. Solve for the ff. probabilities:
  • P (345 < x-bar < 540)
  • P (490 < X-bar < 504)
  • P (287 < X-bar < 490)
  • P (656 < X-bar < 720)
  1. Construct the 95% CI for mu using the X-bar of the sample above.  
  2. Construct the 95% CI for X-bar = 505.
