Question

Use a t-test to test the claim about the population mean

at the given level of significance

using the given sample statistics. Assume the population is normally distributed.

Claim:

μ=51,700;

α=0.10

Sample statistics:

x=52,912,

s=1800,

n=20

Click the icon to view the t-distribution table.

What are the null and alternative hypotheses? Choose the correct answer below.

H0:

μ=51,700

Ha:

μ≠51,700

Your answer is correct.

H0:

μ≥51,700

Ha:

μ<51,700

H0:

μ≤51,700

Ha:

μ>51,700

H0:

μ≠51,700

Ha:

μ=51,700

Check Answer

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.
