A local road was designed to handle a daily mean of 200 Ccars. The local city council is concerned that the road it getting more traffic than it was designed to handle. A recent sample of 50 days found a sample mean of 206 cars per day and a sample standard deviation of 33 cars per day. We will perfrom a hypothesis test to determine if this is strong evidence that the mean number of daily cars is more than the road was designed to handle. Define your variable. O Let u be the mean number of of cars that use the road on the sampled days. O Let p be the proprotion of cars in the sample that use the road. O Let u be the mean number of cars that use the road on a daily basis. O Let p be the proportion of cars that use the road. Write your hypotheses: Ho: ? 0 HA: ?0 Find the P-value: Type your answer as a decimial rounded to three decimal places. Do not type a percentage or a percent sign. P-value=| Using an a level of 5%, you should O Accept Ho Reject H, and Accept HA O Fail to Reject Ho

They all go together with the question.
Transcribed Image Text:A local road was designed to handle a daily mean of 200 cars. The
local city council is concerned that the road it getting more
traffic than it was designed to handle. A recent sample of 50
days found a sample mean of 206 cars per day and a sample
standard deviation of 33 cars per day. We will perfrom a
hypothesis test to determine if this is strong evidence that the
mean number of daily cars is more than the road was designed
to handle.
Define your variable.
O Let u be the mean number of of cars that use the road on
the sampled days.
O Let p be the proprotion of cars in the sample that use the
road.
Let u be the mean number of cars that use the road on a
daily basis.
o Let p be the proportion of cars that use the road.
Write your hypotheses:
Ho: ? 0
Find the P-value: Type your answer as a decimial rounded to
three decimal places. Do not type a percentage or a percent
sign.
P-value=|
Using an a level of 5%, you should

State your conclusions:
We
o do not
O do
have strong evidence that the
O proportion of cars that use the road on a daily basis in now
less than 200
O mean number of of cars that use the road on a daily basis is
greater than 200
mean of cars that use the road in the sample is less than
206
mean of book cars that use the road in the sample is greater
than 206
mean number of of cars that use the road on a daily basis is
less than 200
Is this evidence that the road is getting more traffic than it was
designed to handle?
O No
Yes
