A 100(1 x)% confidence interval for the mean of a normal population when the value of a is known is given by (x-Zα/2 σ Vn x + ²a/2* √n). By how much must the sample size n be increased if the width of the CI above is to be halved? Halving the length requires n to be increased by a factor of If the sample size is increased by a factor of 49, what effect will this have on the width of the interval? Increasing the sample size by a factor of 49 will ---Select-- the length by a factor of
