Redo #19, only this time assume the value 1.2 is the population standard deviation. Then, state this interval below within an interpretive sentence tied to the given context.

19. FHSU wants to know if all their students tend to drink more coffee during finals week than the usual xbar 3.8 semester average (of 3 cups per week). They ask a random sample of 75 students how many cups of s 1.2 coffee they drink during finals week and find the average to be 3.8 cups with a standard deviation of 1.2 n 75 cups. Construct a 95% confidence interval to estimate the population mean for finals week. State cl 0.95 this interval below within an interpretive sentence tied to the given context. alpha 0.05 We are 95% confident that the true population mean of the number of cups of coffee fhsu students alpha/2 0.025 drink during finals week lies between 3.524 and 4.0761. 1-Ipha/2 0.975 t-value 1.992543495 moe 0.276094926 3.523905074 4.076094926
