paired t-test is more powerful because it utilizes information
The"t" test, (called the "small 't' test, to distinguish it from the large 'T' test) is a test for deviation from a known norm, using a smaller sample set than the one required by the large T test. It is said to have been developed by the head of quality control at the Guinness Brewery in Ireland.
d
The Independent Samples T Test compares the mean scores of two groups on a given variable.
In a general t-test, there is no relationship between the members of one sample and the other. In a paired t-test they are connected in some way so that they are likely to give similar outcomes. This means that more of the difference between them can be attributed to the "treatment".
no t test is similar to z test because t test ie used for unknown observation and z is for the medicne
a t test is used inplace of a z-test when the population standard deviation is unknown.
t-test is the statistical test used to find the difference of mean between two groups

t-test

That is the correct spelling of the noun cattle (more often used as plural than singular).
No, don't use a single t-test to compare the means of 3 or more groups. Use ANOVA.

t test is used when- a) variables are studied b)the size of sample is a small one.(n<30) chi square test is studied when a) attributes are studied
