Explanation / Answer

Solution:
Null hypothesis H0: p=1.9% or 0.019
Alternative hypothesis H1: p>1.9% or 0.019
Standard error can be calculated as. = sqrt((0.019*(1-0.019))/600) = 0.005573
Xbar = 21/600 = 0.035
Z = (0.035-0.019)/0.005573 = 0.016/0.005573 = 2.8709
so p-value is 0.00207
Here alpha = 0.1
Here we can see that p-value is less than alpha value so we will reject the null hypothesis and accept the alternate hypothesis. so this model is significant.
