In a study of the accuracy of fast food drive-through orders, one restaurant had 37 orders that were not accurate among 304 orders observed. Use a 0.10 significance level to test the claim that the rate of inaccurate orders is equal to 10%. Does the accuracy rate appear to be acceptable?
Identify the null and alternative hypotheses for this test. Choose the correct answer below.
A. H0:p=0.1 and H1: p<0.1
B. H0: p≠0.1 and H1: p=0.1
C.H0: p=0.1 and H1: p>0.1
D. H0: p=0.1 and H1:p≠0.1
The test statistic for this hypothesis test is ___
Identify the conclusion for this hypothesis test.
Does the accuracy rate appear to be acceptable?
Below are the null and alternative Hypothesis,
Null Hypothesis, H0: p = 0.1
Alternative Hypothesis, Ha: p ≠ 0.1
Test statistic,
z = (pcap - p)/sqrt(p*(1-p)/n)
z = (0.1217 - 0.1)/sqrt(0.1*(1-0.1)/304)
z = 1.26
P-value Approach
P-value = 0.2077
As P-value >= 0.1, fail to reject null hypothesis.
Yes, the accuracy appears acceptable
