I want to see that you can show all the steps for the P-value method of Hypothesis Testing. Problem 3 goes back to Confidence intervals from Chapter 7. Problem 4 reviews several chapters. 1. Some people are concerned that new tougher standards and high stakes tests adopted in many states may drive up the dropout rate. The National Center for Education Statistics reported that the high school dropout rate for the year 2000 was 10.9%. One school district, whose dropout rate has always been very close to the national average, reports that 210 of their 1782 students dropped out last year. Use this sample data and a 0.05 significance level to test the claim that the national high school dropout rate is now greater than 10.9%. Show all the steps of your hypothesis test including a) the claim being tested,b) the null and alternative hypothesis, c) the test statistic, d) the p value, e) initial conclusion, and f a final conclusion about the original claim.Explanation / Answer
a)
Claim : Ha : p > 10.9
b)
H0 : p = 0.109
Ha : p > 0.109
c)
P = 210/1782 = 0.1178 , n =1782
z = ( P -p)/sqrt(p*(1-p)/n)
= (0.1178 - 0.109)/sqrt(0.109*(1-0.109)/1782)
= 1.1920
d)
p value = 0.1166
e)
Do not reject the null hypothesis
f)
There is not sufficient evidence to support the claim that the national high schooldropout rate is now greater than 10.9%
