Question

Select all assumptions made when conducting a hypothesis test for a proportion. There may be more than one correct answer.
A. equal or constant variance
B. observations must be normally distributed
C. normally distributed residuals
D. must have > 30 observations
E. 10+ expected successes and failures
F. no extreme skew or outliers
G. observations should come from a symmetric distribution
H. linearity
I. heteroskedasticity
J. dependent observations
K. independence (sample size < 10% of population + random sample)
L. 10+ observed successes and failures
M. None of the above

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.
