Answer:
Brad in total drove approximately 361 miles.
Step-by-step explanation:
Renting Cost per day of car = $26. 95
Cost per mile= $0.33
So, cost of renting car 3 days = 3 x $26. 95 = $80.85
Total money spent on the trip = $80.85
So, the actual spent money on distance = Total money spent - The renting charge
= $200 - $80.85 = $119.15
So, Distance travelled =
=
or, number of miles traveled = 361
So, Brad in total drove approximately 361 miles.
<h2>Answer with explanation:</h2>
Let be the average starting salary ( in dollars).
As per given , we have
Since is left-tailed , so our test is a left-tailed test.
WE assume that the starting salary follows normal distribution .
Since population standard deviation is unknown and sample size is small so we use t-test.
Test statistic : , where n= sample size ,
= sample mean , s = sample standard deviation.
Here , n= 15 , , s= 225
Then,
Degree of freedom = n-1=14
The critical t-value for significance level α = 0.01 and degree of freedom 14 is 2.62.
Decision : Since the absolute calculated t-value (2.07) is less than the critical t-value., so we cannot reject the null hypothesis.
Conclusion : We do not have sufficient evidence at 1 % level of significance to support the claim that the average starting salary of the graduates is significantly less that $42,000.
