What is the difference between a Menu 6,6,3 and Menu 6,7,3. one is confidence interval, and the other is a Stat test, but I dont know what that means.

When I did the tally’s for my chart the numbers were too large for the classes ?

There is another way of doing this with the n nspire cx2 that looks the same, but with hitting menu,6,3 then selecting sample or pop. I dont understand really whyh it coulld not be added into the calculation. When doing Var, and Std it seems like will likely be calculated at the same time and displayed with the mean.

what if the question doesnt have any data set but asks for variance and deviation for samples of the following (n=8, Ex^2=87,Ex=26)

I had no idea you could insert 'Z' value into the NORM.DIST function. That's clever, thank you.

I have come across a book that provided an amazing shortcut for these questions. It suggested that we imagine creating a square with the given perimeter (2500 yd). Therefore, the side length of the square would be 625. Subsequently, we just need to calculate the area of this square, which is straightforwardly obtained by squaring 625, yielding the identical solution of 390625.

Yes I have a question about give example of empty or null set and define it
@MathandStatsHelpАй бұрын
An empty set (aka null set) is a set that doesn't contain anything. For example, rolling a 7 on a standard six sided die is impossible to happen, so the set of numbers that match rolling a 7 would be a null set. You can either represent the null set as a circle with a line drawn through it or { }. If nothing matches the description, then it is null.

Thanks for the information

I can be wrong here but you made a slight error. For One-tailed test, you reject H0 when p<alpha and reject if p=>alpha(not 100% sure but I checked multiple sources). For two-tailed test, you reject H0 at 2*p<alpha.
@MathandStatsHelpАй бұрын
The text I teach from uses p-value<= alpha, means reject Ho. If p> alpha, Fail to Reject Ho. For two tail tests, the p-value is calculated by doing 2*the probability of getting the standardized test statistic. For this one, since the p-value is given, it doesn't matter the tail of the test.
