Step 1:
NULL hypothesis : P=0.5
Alternative hypothesis: P>0.5
Step 2: =0.01
Step 3:
Let n=sample size=11,000=number car crashes.
X=Number of car crashes occur with in 5 miles=5709
p =x/n=5709/11000=0.519
the test statistic is
Where Z Is standrad normal variate.
= -0.0003
Step 4: the critical value of Z at level of significance 0.01 is 2.33
The calculated value of Z Is less than critical value of Z.
We accept NULL Hypothesis.
P=0.5
There no sufficient evidence to accept claim.
