The claim is that for 12 AM body temperatures, the mean is μ > 98.6°F. The sample size is n= 5 and the test statistic is t = 2.237. What is the P-value?

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:

the correct answer is c

(5x-1)^2= (5x)^2-2(5x)×1+(1)^2=25x^2-10x+1
