Question

From a sample of one hundred forty nursing mothers it was determined that during their first trimester they spend an average of three thousand one hundred and twenty dollars and a standard deviation of five hundred and seventy seven dollars. Assuming the amount spent is normally distributed construct a confidence interval for the population mean, μ at the ninety two percent confidence level.

	a.	($3034, $3205)
	b.	($3019, $3220)
	c.	($3028, $3211)
	d.	($2910, $3330)

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.
