Answer:
<em>Null Hypothesis</em>: H₀ : μ < 214 miles
<em>Alternative Hypothesis :H₁</em>: μ> 214 miles
The calculated value |t| = 1.319 < 3.4966 at 0.01 level of significance
Null hypothesis is accepted
The average daily travel distance is less than 214 miles
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that the size of the sample 'n' = 12
The mean of the Population = 214 miles
The mean of the sample = 198 miles
The standard deviation of the sample = 42 miles
Level of significance = 0.01
<u><em>Step(ii):-</em></u>
Null Hypothesis: H₀ : μ < 214 miles
Alternative Hypothesis :H₁: μ> 214 miles
Test statistic
|t| = |- 1.319| = 1.319
Degrees of freedom = n-1 = 12 -1 =11
critical value
The calculated value |t| = 1.319 < 3.4966 at 0.01 level of significance
Null hypothesis is accepted
The average daily travel distance is less than 214 miles
