Question

The data below gives data comparing the amount of money someone says they want to spend on a new car and how much they end up spending on a new car. Test the claim that people spend more than they say they want to at a 5% level. Assume everything is normally distributed.

How much they want to spend (in 1,000's) 30,25,10,30,45,60,30,25,20

How much they actually ended up spending (in 1,000's) 35,18,12,32,35,75,32,26,18

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.
