Question

Miniature Golf Scores A large group of friends went miniature golfing together at a par

course and decided to play on two teams. A random sample of scores from each of the two teams is shown. At

=α0.01

, is there a difference in mean scores between the two teams? Use the

-value method and a TI-83 Plus/TI-84 Plus calculator. Assume the variables are normally distributed and the variances are unequal.

Team 1	47	55	57	49	62	54	61	46
Team 2	53	49	47	46	42	50	43	44	48

(a) State the hypotheses and identify the claim with the correct hypothesis.

(b) Find the

-value.

(c) Make the decision.

(d) Summarize the results.

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.
