How to Do a One Tailed T-Test in Statistics

In this paper I am going to suffice a champion-tailed, one-sample t¬- rill in order to try on the deceitful surmise that the modal(a) number of ounces of metric grain per stroke equals sixteen. A shaper of a particular brand of grain maintains in that location is an sightly of sixteen ounces of cereal per loge. On the other hand, a consumer free radical asserts the average is fewer than sixteen ounces per box. The consumer concourse is going to deposit a class action cause for false announce if the average is fewer than sixteen ounces per box.

I came up with numbers ranging from 12.4 universe the lowest to 18.4 being the highest cant of the cereal. I then used the one-tailed, one-sample t test to test the null hypothesis that the average number of ounces of cereal per box equals sixteen. After completing the one-tailed, one-sample t test I compared the of import level to the significance and firm to retain the null hypothesis.
