Figure 4.14 shows a randomization distribution for testing H 0 : Î¼ = 50 vs H a

Question:

Figure 4.14 shows a randomization for testing H₀: Î¼ = 50 vs H_a: Î¼ > 50. In each case, use the to decide which value is closer to the p-value for the observed sample mean.

(b) The p-value for x = 54 is closest to: 0.10 or 0.30?
(c) The p-value for x = 63 is closest to: 0.05 or 0.50?

A randomization distribution based on 1000 simulated samples is given along with the relevant null and alternative hypotheses. Which p-value most closely matches the observed statistic?

Distribution
The word "distribution" has several meanings in the financial world, most of them pertaining to the payment of assets from a fund, account, or individual security to an investor or beneficiary. Retirement account distributions are among the most...
