Question

A reseacher found r = -0.5 based on a sample size of 20 pairs of observations. Using table I is the data significate testing H0: = 0?

The data is significant at both = 0.05 and at = 0.01

The data is not significant at = 0.05 and but is significant at = 0.01

The data is significant at = 0.05 but not at = 0.01

The data is significant at neither = 0.05 nor = 0.01

The data is significant at both = 0.05 and at = 0.01

The data is not significant at = 0.05 and but is significant at = 0.01

The data is significant at = 0.05 but not at = 0.01

The data is significant at neither = 0.05 nor = 0.01

P =0 HENCE P <0.05 AND P<0.01 therefore H0 is rejected and it is significant.

Hence the correct option is

The data is significant at both alpha = 0.05 and at alpha = 0.01
