A local company makes a candy that is supposed to weigh 1.00 gram. A random sample of 25 pieces of candy produces a mean of 0.996g with a standard deviation of 0.004g. If candy weight is normally distributed, how many pieces of candy must we sample if we want to be 99% confident that the sample mean is within 0.001g of the true mean? Select one: Rla. O b. 62 126 O c. 47 Od. 69 O e. 44
