Explanation / Answer

Ans:

Option A is correct.

sample mean=755

standard deviation=300.441

t=(755-1000)/(300.441/sqrt(6))

t=-1.997

df=6-1=5

p-value=tdist(1.997,5,1)=0.0511

As,p-value>0.01,we fail to reject H0.There is not sufficient evidence to support the claim that sample is from a population with mean less than 1000.
