This Question: 8 pts Tests 250 pts Time Remai A soccer ball manufacturer wants to estimate the mean crcunference of soccer balls within 0.1 in (a) Determine the m nmurn sample sze rel red to construct a 99% confi e ce terval fr be populism mean Assan e de popda on standard de tirs o 25 i b) Repeat part (a) using a standard deviation of 0 30 in Whsich standard deviation requires a arger sample size? Explam o stddiai of oto m ah t (a) The man m sample sue required to construct a 99% confidence interval usee populat on standad devat on orozni Round up to the nearest integes.) (b) The manum sample sue tequred to construct a 99% confolence interval using a standard deviation of 0 Win is bah bls (Round up to the nearest integer ) A population standard deviation ofin requires a larger sample size. Due to the increased variability in the popalationa Ei, re ies alarger sample size Detode mcreased vanabity the population, a Apopulation standard devia ion of sample sire is needed to ensure the desired accuracy
