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.
Answer:
x=8.4
Step-by-step explanation:
use tangent to solve the equation which is opposite/adjacent and set up the proportion

the cross multiply to get x=tan(35)×12 then multiply that to get x=8.4

Answer:
a. P) = 0.25
b. P) = 0.25
c. P) = 0.5
Step-by-step explanation:
a) 1/4 as 1/2 x 1/2 = 1/4 = 0.25 This becomes reduced as we are multiplying one complete probability journey by another complete probability journey.
b) see above as 1/2 x 1/4 and 1/4 x 1/2 = 2.5 = 1/4 = 0.25
or we can Set to 1 and 1 - 3/4 = 1/4. = 0.25.
c) 1/2 as half of the journeys have traffic jams so its 1 - 1/2 = 1/2 = 0.5
