Ho: μ = 400 Ha: μ< 400 The p-value for the hypothesis test is Your answer should be rounded to 4 decimal places. WebThe p-value is for a one-sided hypothesis (one-tailed test), allowing you to infer the direction of the effect (more on one vs. two-tailed tests). However, the probability value for the two-sided hypothesis (two-tailed p-value) is also calculated and displayed, although it should see little to no practical applications.

WebP Values. The P value, or calculated probability, is the probability of finding the observed, or more extreme, results when the null hypothesis (H0) of a study question is true – the definition of ‘extreme’ depends on how the hypothesis is being tested.

WebP values can be "hacked" to give a significant result when one doesn't actually exist, leading to unreproducible research. Other times researchers approach hypothesis testing backwards, by letting the P value decide the hypothesis after the fact. Confidence intervals give a range of possibilities that are more informative than a P value.
