A manufacturer claims that the mean lifetime of its lithium batteries is less than 1500 hours. A homeowner selects 25 of these batteries and finds the mean lifetime to be 1480 hours with a
standard deviation of 80 hours. Test the manufacturer's claim. Use α = 0.10.
A. 
Pvalue = 0.112 > 0.10; do not reject H0; There is not enough evidence support the claim, that mean is less than 1500. 

B. 
Pvalue = 0.112 > 0.05; do not reject H0; There is not enough evidence support the claim, that mean is less than 1500. 

C. 
Pvalue = 0.022 > 0.05; reject H0; There is enough evidence support the claim, that mean is less than 1500. 

D. 
Pvalue = 0.112 > 0.10; do not reject H0; There is not enough evidence support the claim, that mean is less than 1500.
