Question

Suppose the age that children learn to walk is normally distributed with a mean 11 months and standard deviation 2.2 month. 35 randomly selected people were asked what age they learned to walk.

What is the probability that one randomly selected person learned to walk when the person was between 10.8 and 11.1 months old?

For the 35 people find the probability that the average age that they learned to walk is between 10.8 and 11.13 months old?

Find the IQR for the average first time walking age for groups of 35 people. For part d, is the assumption that the distribution is normal necessary? Yes or No

Q1 = how many months

Q3 = how many months

IQR = how many months

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.
