Hi Guys,
This video will show you how to calculate the hypothesis test using the Ti-84.
This is the problem:
The height of 12 supermodels were measured. Their mean is 69.6 in and a standard deviation of 2.4.
Test the claim that supermodels have heights greater than the mean 62.3 in for women from the general population

  • you use z test if you're given the population standard deviation. she probably just calculated her sample standard deviation

  • Why the t value given as this process is not equal to the t value by using inverseT distribution???

  • Why are you using T test if the standard deviation is given? You use t test when it’s not given.

    @MerkBonez@MerkBonez6 жыл бұрын

    • standard deviation given is from the sample, not the population, thus a T test
