Question

Listed below are the lead concentrations in

muμg/g

measured in different traditional medicines. Use a

0.010.01

significance level to test the claim that the mean lead concentration for all such medicines is less than

1515

muμg/g.

Assume that the lead concentrations in traditional medicines are normally distributed.

22.5

9.5

22.5

12.5

13.5

10.5

What are the null and alternative hypotheses?

Upper H 0H0:

muμequals=1515

muμg/g

Upper H 1H1:

muμless than<1515

muμg/g

Your answer is correct.

Upper H 0H0:

muμequals=1515

muμg/g

Upper H 1H1:

muμgreater than>1515

muμg/g

Upper H 0H0:

muμgreater than>1515

muμg/g

Upper H 1H1:

muμless than<1515

muμg/g

Upper H 0H0:

muμequals=1515

muμg/g

Upper H 1H1:

muμnot equals≠1515

(Round to two decimal places as needed.)

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.
