Question

Ten randomly selected people took an IQ test A, and next day they took a very similar IQ test B. Their scores are shown in the table below.

Person	A	B	C	D	E	F	G	H	I	J
Test A	82	101	94	105	111	88	99	123	118	79
Test B	84	100	93	111	114	92	101	125	116	79

Consider (Test A - Test B). Use a 0.05 significance level to test the claim that people do better on the second test than they do on the first, which is testing d=(Test A - Test B)<0

(round your answer to four decimal places)

The test statistic is

P value is

Is there sufficient evidence to support the claim that people do better on the second test?
