Question

A data set includes data from

500500

random tornadoes. The display from technology available below results from using the tornado lengths​ (miles) to test the claim that the mean tornado length is greater than

2.32.3

miles. Use a

0.050.05

significance level. Identify the null and alternative​ hypotheses, test​ statistic, P-value, and state the final conclusion that addresses the original claim.

What are the null and alternative​ hypotheses?

A.

Upper H 0H0​:

muμequals=2.32.3

miles

Upper H 1H1​:

muμgreater than>2.32.3

miles

B.

Upper H 0H0​:

muμequals=2.32.3

miles

Upper H 1H1​:

muμless than<2.32.3

miles

C.

Upper H 0H0​:

muμequals=2.32.3

miles

Upper H 1H1​:

muμnot equals≠2.32.3

miles

D.

Upper H 0H0​:

muμless than<2.32.3

miles

Upper H 1H1​:

muμequals=2.32.3

miles

Answer 1

This is the right tailed test .

The null and alternative hypothesis is

H₀ : $\mu$ = 2.3

H_a : $\mu$ > 2.3

Option A
