The test statistics based on the information given will be -0.6329.
It should be noted that that test statistics simply means a method that's used in statistics for hypothesis testing.
From the information given, a standard weight that is known to weigh 1 gram is repeatedly weighed 4 times and the resulting measurements (in grams) are: {0.95,1.02, 1.01, 0.98}.
The computed standard deviation is 0.p
0316, the sample size is 4, degree of freedom is 3. The test statistic will be:
= (0.99 - 1)/(0.0316/✓4)
= -0.6329
In conclusion, the test statistics based on the information given will be -0.6329.
