Question

The weights of Australian Cattle Dogs are normally distributed with a mean of 25 kg and a
standard deviation of 4 kg.
What is the probability (%) that a randomly selected dog weighs between 23 kg and 32 kg? Round to two decimal places

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.
