a. 
The probability of getting this result, or a more extreme result, given H_{0} is true, is 0.037. It is lower than the 0.05 significance level. Therefore, there is sufficient evidence to reject H_{0}.


b. 
The probability of getting this result, or a more extreme result, given H_{0} is true, is 0.037. It is lower than the 0.05 significance level. Therefore, there is not sufficient evidence to reject H_{0}. 

c. 
The probability of getting this result, or a less extreme result, given H_{0} is true, is 0.05. It is higher than the 0.037 significance level. Therefore, there is not sufficient evidence to reject H_{0}.


d. 
The probability of getting this result, or a less extreme result, given H_{0} is true, is 0.05. It is higher than the 0.037 significance level. Therefore, there is sufficient evidence to reject H_{0}.
