... mean is x = 50 months. Suppose that the lifetimes for tires of this brand follow a normal distribution, with unknown mean µ and standard deviation σ = 5 kg. Find a 95% confidence interval for µ. During class we found that the 95% confidence interval for the population mean, µ, was (48.04, 51.96). St ...

... I) At any < .05, we can reject the null hypothesis that the true mean is 1000. II) If a 99% confidence interval for the mean were determined here, the numerical value 972 would certainly lie in this ...
