Question

a) The number of raisins in a randomly chosen Jamaican spice bun can be modeled as a
random variable having a Poisson distribution with mean 5.2. Find the probability that a
randomly chosen Jamaican spice bun has exactly10 raisins. Ensure that you have defined
the variable of interest and A bank official finds that the length of time customers wait to be served by teller are
approximately normally distributed with a mean of 5 minutes and a standard deviation of
3 minutes. What probability that a customer has to wait for at least 6.7 minutes?

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.
