Problems on unknown variable value c and given probability (for normal random variable X), do the following: Reduce the problem to P (X < c) = a known probability.The Invnorm Calculator can instantly calculate the inverse normal distribution probability of the given values. First, we plug in our z-score probability value, 0.7. After inputting the probability, we move on and input the mean μ value, 0, into the Calculator. We enter the last input, the standard deviation σ, 1.Comparing the test statistic and critical value, students decide whether to reject or fail to reject the null hypothesis. Then they use the ShadeNorm command to find the P -value, confirming their decision about the hypothesis. At the end of this activity, students will be able to compare two means for a real-life scenario.

The pdf is the probability distribution function, and the cdf is the cumulative distribution function. If you don't know what those are, I suggest googling those names. In short, the cdf is the area under the curve of the pdf. The total area under the pdf curve is 1, so the cdf asymptotically approaches 0 on the left towards negative infinity ...TI-84: x 1 = invNorm((1–area)/2,µ,σ) x 2 =invNorm(1–((1–area)/2),µ,σ) This page titled 6.7: Chapter 6 Formulas is shared under a CC BY-SA 4.0 license and was authored, remixed, and/or curated by Rachel Webb via source content that was edited to the style and standards of the LibreTexts platform; a detailed edit history is available ...Attention!
