Find the P-value for all
1. the test statistic in a right-tailed test is z= 0.52
2. the test statistic in a two-tailed test is z= 1.95
3. In a sample of 88 children selected randomly from on town, it is found that 8 of them suffer from asthma. Find the p-value for a test of the claim that the proprtion of all children in the town who suffer from asthma is equal to 11%

Hi. This is a probability question. Start here http://www.answers.com/P-value?cat=technology&gwp=13
From the web "More technically, the p-value of an observed value t-observed of some random variable T used as a test statistic is the probability that, given that the null hypothesis is true, T will assume a value as or more unfavorable to the null hypothesis as the observed value t-observed. "More unfavorable to the null hypothesis" can in some cases mean greater than, in some cases less than, and in some cases further away from a specified center."

You need a p-value table for this. If you have the table, just look it up.
