Question

To assess the accuracy of a laboratory scale, a standard weight that is known to weigh 1 gram is repeatedly weighed 4 times. The resulting measurements (in grams) are: {0.95,1.02, 1.01, 0.98} Carry out the appropriate hypothesis test to see if the scale is inaccurate. What is your Test Statistic

Answers

    What is test statistics?

    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.
