Decide whether the normal sampling distribution can be used. If it can be used, test the claim about the population proportion p at the given level of significance α using the given sample statistics. Claim: p ≠ 0.24; α = 0.01; Sample statistics: p^hat equals = 0.22, n = 200. a). Can the normal sampling distribution be used? Yes, because the np and nq are great than or equal to 5. b). State the null and alternative hypotheses. H0: p = 0.24 Ha: p does not equal 0.24 Determine the critical value(s). Select the correct choice below and, if necessary, fill in the answer box to complete your choice.

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.
