Answer:
A)
B)
Step-by-step explanation:
A) We are given the following in the question:
At most 42% of car crashes occur within 2 miles of the motorists home
p = 42% = 0.42
We design the null and the alternate hypothesis in the following manner:
At most 42% of car crashes occur within 2 miles of the motorists home which means car crashes should be less than equal to 42% but not greater than 42%.
The null hypothesis sates that 42% or less car crashes occur within 2 miles of the motorists home.
The alternate hypothesis state that more than 42% of car crashes occur within 2 miles of the motorists home.
B) We have to find the value of z critical for given conditions
We are performing a two tailed test.
Alpha, α = 0.001
Calculating the z value from the standard z-table. We find the value from the table under the level of significance 0.001
The value obtained is used as the acceptance region for the null hypothesis.
The obtained acceptance region can be written as:
If the calculated z score lies in this region we accept the null hypothesis. If not we reject the null hypothesis.
