Answer:
Null hypothesis: p= 0.65
Alternative Hypothesis: p < 0.65
Explanation:
Below are the null and alternative hypothesis,
Null hypothesis: p= 0.65
Alternative Hypothesis: p < 0.65
Test statistic for text of significance
z = (pcap –p)/ ![\sqrt{ [p*(1-p)/n]}](https://tex.z-dn.net/?f=%5Csqrt%7B%20%5Bp%2A%281-p%29%2Fn%5D%7D)
z = (0.576 – 0.65)/ ![\sqrt{[0.65×1-0.65)/125]}](https://tex.z-dn.net/?f=%5Csqrt%7B%5B0.65%C3%971-0.65%29%2F125%5D%7D)
z = 1.73
P- value Approach
p-value = 0.0414
As P-value < 0.05, we reject the null hypothesis
