Which statement is best represented by the inequality d>11?
2 answers:
For this case we have the following inequality:
Assuming that "d" is the variable that represents the number of hours worked by Mo during this week, we have that the hours were greater than 11, according to the inequality sign.
So, the correct option is:
Mo worked more than 11 hours this week.

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
