Answer:
Yes. There is sufficient eveidence to support the claim that Wilmington resident's earn more than the national average
Step-by-step explanation:
Given the following;
#We set our hypothesis as:
The rejection region of either hypothesis:
, we determine the critical values for this probability in the T distribution table;
=>We reject for all values greater than 1.833, t>1.833.
#We now determine the value of the test statistic as:
We find that:
Hence, there is sufficient eveidence to support the claim that Wilmington resident's earn more than the national average.
40 garments need to be dry cleaned for the two companies to have the same cost.
<h3>Linear equation</h3>
Linear equation is in the form:
y = mx + b
where y, x are variables, m is the rate of change and b is the initial value of y.
Let f(x) represent the cost for dry cleaning at Company 1. Hence using the points:
- (5, 115.25) and (15, 155.75)
Let g(x) represent the cost for dry cleaning at Company 2. Hence using the points:
- (5, 45.25) and (15, 105.75)
For the cost to be the same:
4.05x + 95= 6.05x + 15
x = 40
40 garments need to be dry cleaned for the two companies to have the same cost.
