Question

1) A researcher reported that the mean time for a Honda CRV to go from 0 to 55 miles per hour was 6.8 seconds.

If you want to set up a statistical test to challenge the claim of 6.8 seconds, what would you use for the null hypothesis?

Answer 1

Answer #1

Solution:

Answer is

µ = 6.8 seconds

Option b. correct.

Explanation:

Claim by researcher : " mean time for a Honda CRV to go from 0 to 55 miles per hour was 6.8 seconds."

i.e. mean µ = 6.8 seconds

Valid signs in null hypothesis H₀ are = , and

Valid signs in alternative hypothesis H_A are , < and >

So , the null hypothesis is

µ = 6.8 seconds

Option b. correct.
