Question
A. Consider the population of integers from 1 to 1000 whose = 500.5 with sigma unknown:
- 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
- What is the mean of the sampling distribution of means?
- Which distribution is more appropriate to use: Z or t? Why?
- Solve for SE. Use the correct statistical symbol.
- Graph the sampling distribution of means. Label the mean values up to +0 from the center.
- 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)
- Construct the 95% CI for mu using the X-bar of the sample above.
- Construct the 95% CI for X-bar = 505.
