The test statistic under the null hypothesis of is when the sample mean is for a random sample of size 15 from a normal population with unknown variance. The given statement is true.
For a random sample of size 15 from a healthy population with known variation. the statistical measure under test for the null hypothesis.
Even when the population variance is known and the sample size is modest, the Z-test can be used.
The given statement is true.
Hypothesis :
In statistics, hypothesis testing is used to identify the variance in the group of data that results from genuine variation. Based on the presumptions, the sample data are taken from the population parameter. The hypothesis can be divided into many categories. A hypothesis is described in statistics as a formal statement that explains the relationship between two or more variables belonging to the specified population. It aids the researcher in converting the stated issue into an understandable justification for the study's findings. It provides examples of various experimental designs and guides the investigation of the research procedure.
