Explanation Given info: The data shows that the earthquake magnitudes and the level of significance is 0.01. Calculation: The claim that the median is equal to 1.00 is null hypothesis. Thus, the alternative hypothesis is the median is not equal to 1.00. The hypotheses are given below: Null hypothesis: H 0 : The median is equal to 1.00. Alternative hypothesis: H 1 : The median is not equal to 1.00. Test statistic: The number of positive and negative signs is obtained by subtracting the magnitude by 1. The test statistic can be calculated as follows: Magnitude Difference (Magnitude–1) 0.7 –0.3 2.2 1.2 1.54 0.54 1.01 0.01 1.62 0.62 1.28 0.28 0.92 –0.08 1 0 1.49 0.49 1.42 0.42 0.74 –0.26 1.98 0.98 1.32 0.32 1.26 0.26 1.83 0.83 0.83 –0.17 1 0 2.24 1.24 0.84 –0.16 1.35 0.35 0.64 –0.36 0.64 –0.36 2.95 1.95 0 –1 0.99 –0.01 1.34 0.34 0.79 –0.21 2.5 1.5 1.42 0.42 0.93 –0.07 0.39 –0.61 1.22 0.22 0.9 –0.1 0.65 –0.35 1.56 0.56 0.54 –0.46 0.79 –0.21 1.79 0.79 1 0 0.4 –0.6 0.7 –0.3 0.2 –0.8 1.76 0.76 1.46 0.46 0.4 –0.6 1.25 0.25 1.44 0.44 1.25 0.25 1.25 0.25 1.39 0.39 From the above table it can be observed that the number of positive signs is 29, the number of negative signs is 20. The sample size that should be used for the sign test is 49. The test statistic( x ) is the minimum of number of positive signs and negative signs. The minimum of 29 and 20 is 20. Thus, test statistic( x ) value is 20. Here, the sample size 49 is greater than 25
