Tim Atten 1 H Nabisco is quality testing oreos and takes a sample of 80 oreos. They want to determine the mean amount of cream being put into oreos by a certain machine. The sample indicates that there is a mean of 4.3g with a standard deviation of roughly, 0.35g. We will assume the values are normally distributed. Determine a confidence 95% confidence interval estimating the mean amount of cream in the machine is distributing. O (4.2221, 4.3779) O (4.1362, 4.3266) O (4.3217, 4.4424) (4.2178,4.3678)
