Use the sign test with a 0.05 significance to test the null hypothesis of no difference. Positive signs: 15; negative signs: 7: ties 1 Is there sufficient evidence to reject the null hypothesis of no difference? Yes, because the test statistic is greater than the critical value. No, because the test statistic is greater than the critical value -Yes, because the test statistic is less than or equal to the critical value. No because the test statistic is less than or equal to the critical value Question 13 Use a 0.05 significance level to test the claim that when the 13th of the month falls on a Friday the number of storms is not affected

Explanation / Answer

as from table for n=15+7 =22 ; critical value is 5 ;

and as test statistic min(7,15) =7 is greater than critical value ; we can not reject null hypothesis

Hence corect option is :

No ; because the test statistic is greater than the crtiical value
