(1 point) A random sample of n measurements was selected from a population with standard deviation σ=18.7 and unknown mean μ Calculate a 95% contidence interval for μ for each of the following situations: (a) n−35,xˉ=70.9 <μ< Round your answers to two decimal places. (b) n=65,xˉ=70.9 <μ< Round your answers to two decimal places. (c) n=95,xˉ=70.9 <μ< Round your answers to two decimal places. (d) In general, we can say that for the same confidence level, increasing the sample size the widin of the confidence intervals. (Enter. "DECREASES". "DOES NOT CHANGE" or "INCREASES", wthout the quotes.)
