lifetime of the battery? What is the p-value? Choose the correct statement out of the following: Select one: O p-value = 0.0122: reject null hypothesis at the 5% significance level but not 1% level O p-value = 0.0122: reject null hypothesis at both 5% and 1% significance levels O p-value = 0.0244: reject null hypothesis at the 5% significance level but not 1% level O p-value = 0.0244: reject null hypothesis at both 5% and 1% significance levels Check

Question

I got the first choice but I'm not too sure

The useful lifetime of a particular battery is a normally distributed random variable with mean u = 40 hours and known standard deviation o = 4 hours. A new chemical composition is introduced aiming to increase the useful lifetime of the battery. It is assumed that the new chemical composition does not affect the standard deviation. After implementing the new process, a random sample of n= 100 batteries has a sample mean useful lifetime of 40.9 hours. Has the new process increased the useful lifetime of the battery? What is the p-value?
