Document Summary

The p-value is also called the observed significance level of the test. If the p-value is between 1% and 5%, the results are said to be significant, and if p is 1% or less, the results are deemed highly significant. If p is small enough, the null hypothesis is said to be rejected in favor of the alternative hypothesis. The nature of the box-model tells us how to do this: comment: in many scenarios, the test stat follows the normal distribution. To test this belief he begins with : box model: each household in metropolis corresponds to a ticket in a box. The number on the ticket is the number of connected devices in the household. Then he formulates the : null hypothesis: h0: u = 4 and the , alternative hypothesis: ha: u > 4. [1] household in metropolis with income over ,000.
