Is the national crime rate really going down? Some sociologists say yes! They say that the reason for the decline in crime rates
anygoal [31]

Answer:

a) Level of significance \alpha = 0.01

b) Standard normal

p = 0.75

Z = 0.62

c)  

P = 0.5352

d)  

P > \alpha

e) We fail to reject null hypothesis  

Step-by-step explanation:

Let us say

The null hypothesis H_0 is p= 0.70 which means that Probability of arresting male of age ranging between 15 to 34 years is 0.7

Alternate hypothesis H_1 is p not equal to 0.7 which means that Probability of arresting male of age ranging between 15 to 34 years is not equal to 0.7

a) For 1% level of significance \alpha = 0.01

b) Standard normal

n_p > 5\\n_q >5

p = \frac{24}{32} = 0.75

Z = \frac{(0.75-0.70)}{\sqrt{\frac{(0.7*0.3)}{32} } }  = 0.62

c)  

P = 2 * 0.2676 = 0.5352

d)  

P > \alpha

e) We fail to reject null hypothesis  

Hence, there is not enough data to prove that at 1% level of significance the probability of number of male arrested between age 15-34 is  0.70
