In a study of the accuracy of fast food drive-through orders, one restaurant had 36 orders that were not accurate among 322 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?

Step-by-step explanation:

Given that in a study of the accuracy of fast food drive-through orders, one restaurant had 36 orders that were not accurate among 322 orders observed.

Sample proportion = 36/322= 0.112

Hypotheses would be:

(two tailed test at 1% significance level)

p difference = 0.012

Std error =

Test statistic =

p value = 0.48

since p >0.01 we accept null hypothesis

The accuracy rate appears to be acceptable as only 10% are not accurate.

45

step-by-step explanation:

to find a percentage, add a decimal in front and multiply it by the other number.

.25 times 180= 45
