Question

Overall, 60% of parents at a particular school agreed that the genders are equal and should have the same opportunities to participate in sports. In a survey, 500 parents were asked about the importance of sports for both boys and girls.

• Identify the population, the sample, and the sample statistic. Is the sampling distribution normally distributed?

• What is the mean and standard deviation of the sampling distribution? • Find the cutoff for the highest 84% of sample proportions.

• Find the cutoffs for the middle 68% of sample proportions.

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.
