Question

Packets of flour packed by a particular machine have masses which are normally
distributed with mean 500 gram and standard deviation 20 gram. 2% of the packets
are rejected for being underweight and 1% of the packets are rejected for being
overweight.
Estimate the mass of a packet of flour if it is to be accepted.
(i) Determine the median mass of the packets of flour that are accepted.
(ii) Six packets of flour are selected at random, what is the probability that at
least one is accepted?

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
