Answer: There are 24 traffic lights on Berry Boulevard.
Step-by-step explanation:
Since we have given that
Total length of road = 
Number of roads on every
= 2
So, According to unitary method,
In every
, number of roads = 2
In every 1 mile, number of roads = 
So, in every
the number of roads = 
Hence, there are 24 traffic lights on Berry Boulevard.
Answer:
the red one
Step-by-step explanation:
Using the t-distribution, it is found that the test statistic for the hypotheses test is given by:

<h3>What are the hypotheses tested?</h3>
At the null hypotheses, it i tested if the mean difference remains the same, that is:

At the alternative hypotheses, it is tested if it has decreased, hence:
.
<h3>What is the test statistic?</h3>
The test statistic is given by:

The parameters are:
is the sample mean.
is the value tested at the null hypothesis.
- s is the standard deviation of the sample.
The parameters are given as follows:
.
Hence the test statistic is given by:
