Does the data follow standard normal? Suppose the data size is 100. Then, we know, in the interval (0,1), there are 34 numbers, and the same for interval (-1,0); In the interval (1,2), there are 14 numbers, and the same for interval (-2,-1). In the interval (2,infinity), and the interval (-infinity, -2), 2 numbers each. Suppose for your data, you find the numbers in the intervals (-infinity, -2), (-2,-1), (-1,0), (0,1), (1,2), (2, infinity) are, respectively, 1,19,30,30,19,1. Suppose you use one-way Table to test the nomality of your data. The value of test statistic is: O2.3 5.5 0.6.7 8.6

Transcribed Image Text:Does the data follow standard normal? Suppose the data size is 100. Then, we know, in the interval (0,1), there
are 34 numbers, and the same for interval (-1,0); In the interval (1,2), there are 14 numbers, and the same for interval
(-2,-1). In the interval (2,infinity), and the interval (-infinity, -2), 2 numbers each. Suppose for your data, you find
the numbers in the intervals (-infinity, -2), (-2,-1), (-1,0), (0,1), (1,2), (2, infinity) are, respectively,
1,19,30,30,19,1. Suppose you use one-way Table to test the nomality of your data. The value of test statistic is:
2.3
5.5
6.7
8.6
Transcribed Image Text:(continue of 5). Your conclusion at the significance level 0.05, is:
O The data is NOT normal, since the test statistic is big.
O The data is normal, since the test statistic is big.
O The data is NOT normal, since the test statistic is small.
O The data is normal, since the test statistic is small.
