Question

Assuming a random sample of N=12 values taken from a normally distributed population with unknown parameters have the following sample values; 2 9 8 6 9 5 6 4 7 4 9 and 3.
Use the sample information to construct a 95% Confidence Interval estimate for the population mean. [Assume the t-critical value at 5% with df of 11 is 2.201]

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.
