Question

Gentle Ben is a Morgan horse at a Colorado dude ranch. Over the past weeks, a veterinarian took the following glucose readings from this horse (in mg/100ml).

93, 88, 82, 105, 99, 110, 84, 89

Let x be a random variable representing glucose readings taken from Gentle Ben. We may assume x that has a normal distribution, and we know from past experience that the population standard deviation is 12.5 mg/100ml. The population mean glucose level for horses should be 85 mg/100ml (Reference: Merck Veterinary Manual). Do these data indicate that Gentle Ben has an overall average glucose level higher than 85 mg/100ml? Use alpha = 0.05

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.
