7.5: Critical values, p-values, and significance level

WebbA p value refers to the measurement of the value of probability that an observed difference could occur by chance. There exists an inverse relationship among p value and statistical significance. A low p value will correspond to the greater statistical significance of the observed difference and vice versa. What p value is significant? WebbRecall that the P-value is a probability of obtaining a value of the test statistic or a more extreme value of the test statistic assuming that the null hypothesis is true.

Calculate the test statistic: z = p ^ − p 0 p 0 ( 1 − p 0) n. where p 0 is the null hypothesized proportion i.e., when H 0: p = p 0. Determine the critical region. Make a decision.

WebbRealize P (z ≤ -1.83) = P (z ≥ 1.83) since a normal curve is symmetric about the mean. The distribution for z is the standard normal distribution; it has a mean of 0 and a standard deviation of 1. For Ha: p ≠ 26, the P-value would be P (z ≤ -1.83) + P (z ≥ 1.83) = 2 * P (z ≤ -1.83). Regardless of Ha, z = (p̂ - p0) / sqrt (p0 * (1 ... WebbThe p-value tells if a null hypothesis is valid or not. It can be measured in terms of its significance ranging from 0 to 1.
