The mean weight of loads of rock is 47.0 tons with a standard deviation of 8.0 tons. If 25 loads are chosen at random for a weight check, find the probability that the mean weight of those loads is less than 46.5 tons. Assume that the variable is normally distributed.

The mean weight of loads of rock is 47.0 tons with a standard deviation of 8.0 tons. If 16 loads are chosen at random for a weight check, find the probability that the mean weight of those loads is less than 46.0 tons. Assume that the variable is normally distributed. A) 80.85 B) 19.15 C) 30.85 D) 69.15
For any normal distribution, find the probability that the random variable lies within two standard deviations of the mean.
