Question

Suppose we want to test the null hypothesis H₀: p = 0.34 against the alternative hypothesis H₁: p > 0.34. Suppose also that we observed 120 successes in a random sample of 300 subjects and the level of significance is 0.05. What is the distribution of the test statistic for this test?

Select one:

normal distribution with mean 0.5 and variance 0.0007

binomial distribution with n = 300 and p = 0.5

t-distribution with df = 299

standard normal distribution

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.
