Question

In a study of the accuracy of fast food drive-through orders, one restaurant had 36 orders that were not accurate among 334 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 nul and alternative hypotheses for this test. Choose the correct answer below. O A Ho:p0.1 He:p<0.1 OB. Ho: p=0.1 HD>0.1 OCHOD 0.1 HP 0.1 Mo. Ho p=0.1 H, #01 Identity the best statistic for this hypothesis test. The tout statistic for this hypothesis test is Round to two decimal places as needed)
t stat and p-score

Answer 1

p= 0.1 Null hypothesis;HO: Alternative hypothesis;H1: pt 0.1 Sample proportion: p= = 0.107784 Here,x= 36 72 Sample size: n= 334 p(1-P) Standard error: = 0.016415 n 0.1 given Level of significance: Test statistic: p-p z = 0.47 p(1-P) 72 p-value: For = 0.470 the two tailed p-value is 0.6384 Decision: Since p-value > a, we fail to reject HO Conclusion : yes
