Using minitab instead of tables for z values probabilities etc, 5/2/2019 · Using Minitab Express to find a z – score given an area/probability first.
To calculate the Z-score, Minitab first determines proportions of observations that are outside the specification limits based on the nonnormal distribution that you specified for the analysis. The shaded region on this graph represents P 1 , which is the probability that the measurements X are less than the lower specification limit (LSL) using the nonnormal distribution specified for the analysis.
You can use the Z-value to determine whether to reject the null hypothesis. To determine whether to reject the null hypothesis compare the Z-value to your critical value, which can be found in a standard normal table in most statistics books. The critical value is Z 1-?/2 for a two sided test and Z 1-? for a one sided test. If the absolute value of the Z-value is greater than the critical value, you reject the null.
CTRL+ SHIFT+ F(Windows) ?+ ?+ F(Mac) Close Message. ESC. Minitab Express can also be used to find the values that separate a given proportion of the normal distribution. This procedure can be used to find the z* multiplier when constructing a confidence interval for any confidence level.
The video shows how to do this with Minitab Express . 2. Find the IQ score which separates the bottom 80% of the adults from the top 20%. In the textbook, we nd the z – score that came closest to a cumulative probability of 0.80 and converted it to an x- score to get 112.6. The video shows how to do this in Minitab Express .
