Question

in a study of the sourcy of fast food drive-through orders, one restaurant had 30 orders that were not sure among 326 orders observed. Use a 0.01 significance level to test the claim that the rate of inaccurate orders is equal to 10%. Does the accuracy rate appear to be acceptable? werdry ruladaterative hypomeses som et Choose the correct answer W. A Hp01 HD01 OB HD.1 H 0.1 OCH D01 OD.

calculated by using P-value ran can be I wo -tailed condition with 7 statistic P-value Mae-1.18) + P(2 >1.18) (:1121-1.18) - P(221,18) - 2ilze-1.187 7 siore 2 left tail avea of Cables of -1.18 from the -1.1 and with a row of 0.08 value Column of 22 (0.119) Plz (118) P1231,8) Fas Z=-18 70-238 P-value Z-1.18 less than the is decision If p-value then level 6 reject the Significance hypo Ho null thesis P- values 0.238 > 2 the so we failed to reject CS Scanned with CamScanner null hypothesis (ro)

Conclusion: There is no Sufficient evidence to warrant to claim support the the rejection that rate of inaccurate orders is equal to 10% Answer evidence there is no Sufficient Since the rate the to disprove theory that 10% is equal to of inaccurate orders not acceptable The accuracy rate is that lower to work The restaurant Should rate is correct - option CamScanner
