#14. Recorded here are the germination times (in days) for 17 randomly chosen seeds of a new type of bean. 10, 14, 16, 14, 20, 16, 17, 16, 11, 12, 11, 17, 13, 21, 19, 17, 15 Assuming that the germination times are normally distributed with a 90% confidence interval for the mean germination time for all beans of this type give the lower and upper limits for the 90% confidence interval . Then give its lower limit and upper limit. Carry your intermediate computations to at least three decimal places in round your answer to one decimal place. Lower limit: Upper limit:

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.
