The sample supports the hypothesis that more than half of the vehicles in South Cedar Niles exceed the speed limit.
p-value = 0.00092
Step-by-step explanation:
To solve this problem, we run a hypothesis test about the population proportion.
Proportion in the null hypothesis
Sample size (n) = 73
Sample proportion (p) = 49/73 = 0.6712
H0:
Ha:
Test statistic =
Calculated statistic =
p-value = 0.00092
Since, p - value is less than or equal to 0.05, the null hypothesis must be rejected. The sample supports the hypothesis that more than half of the vehicles in South Cedar Niles exceed the speed limit.
