A manufacturer claims that the mean lifetime of its lithium batteries is 901 hours. A
homeowner selects 25 of these batteries and finds the mean lifetime to be 880 hours with a
standard deviation of 83 hours. Test the manufacturer's claim. Use α = 0.10.
A. p-value = 0.218 > 0.10; reject the H0; there is not enough evidence to support the claim.
B. p-value = 0.109 > 0.10; reject the H0; there is not enough evidence to support the claim.
C. p-value = 0.218 > 0.10; do not reject the H0; there is enough evidence to support the claim.
D. p-value = 0.109 > 0.10; do not reject the H0; there is enough evidence to support the claim.
