Aʙᴏᴜᴛ Tʜɪs Vɪᴅᴇᴏ – In this video we find the critical region for testing a sample mean using Normal distribution. We test the mean against the critical region to se if there is sufficient evidence to reject the null hypothesis. In the second part, we compare this method to testing the probability against the significance level.

Aʙᴏᴜᴛ Tʜɪs Vɪᴅᴇᴏ – This video looks using the CG50’s Normal distribution features, specifically the Normal cumulative distribution to find probabilities. It covers greater than and less than, ranges of values and shows how we can produce a Normal distribution curve using the calculator. Also covered is saving values in List that can then be used in calculations in Run-Matrix mode.

Aʙᴏᴜᴛ Tʜɪs Vɪᴅᴇᴏ – This video looks at how you can find the mean of a normal distribution given a probability for a certain X value. We make use of the standard Normal distribution, with a standard deviation of 1 and a mean of 0 and find a relevant Z value. We then use this value in the formula for Z values and solve for the mean.

Aʙᴏᴜᴛ Tʜɪs Vɪᴅᴇᴏ – This video looks at the inverse normal distribution function which enables you to find X values, given that you know the probabilities. The inverse feature makes reference to the Area under the normal distribution graph which represents the probability from the Normal cumulative distribution.

Aʙᴏᴜᴛ Tʜɪs Vɪᴅᴇᴏ – Using the Normal Cumulative Distribution, or Normal CD from the Distribution menu, we are able to calculate a range of different probabilities for the normal distribution. Where we have no lower or upper limit, then we need to use a high value, preferably at least 5 standard deviations away from the mean, but there is no reason not to go higher. Also, the video shows two methods of how you can find the probability for a region split between the upper and lower tail of the graph.
