Assume the sample is a random sample from a distribution that is reasonably normally distributed and we are doing inference for a sample mean. Find the area in a t-distribution above 2.3 if the sample has size n=6.

Round your answer to three decimal places.

area = Enter your answer in accordance to the question statement

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.
