Question

Which situation below violate an assumption for conducting hypothesis tests using t statistic?

two observations in a sample are independent from one another

the population from which a small sample (n<30) is obtained for a hypothesis test is normally distributed

the population from which a large sample (n>30) is obtained for a hypothesis test is not normally distributed

None

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.
