Answer:
Step-by-step explanation:
Given that a study found that the average stopping distance of a school bus traveling 50 mph was 264 feet.
Sample taken showed the following results

Since population std deviation is known and sample size is large, z test can be used.

(Left tailed test)
Mean difference = 
Std error = 
Z = test statistic = mean diff/std error
= 
p value = 0.00017
Since p < alpha our 0.05 we reject null hypothesis
There is evidence to show that mean is less than 264 feet
(Assumptions:
Sample are randomly drawn
Sample represents the population
Answer:
4.79
Step-by-step explanation:
all together the total is 38.32
you want to find one so you do
38.32 ÷ 8 = $4.79
hope it helps!

Distance from finish line can be computed by subtracting the amount he has ran from 3. Every minute he runs .5km, and we can use this to create a function to describe this instance.

The distance remaining is equivalent to the minutes multiplied by .5km for each minute subtracted from 3 which is the total distance.
