Q. 10
In a study of Burger King drive-through orders, it was found that 264 orders were accurate and 54 were not accurate. For McDonald’s, 329 orders were found to be accurate while 33 orders were not accurate.
a. Use a 0.05 significance level to test the claim that Burger King and McDonald’s have the same accuracy rates.
b. Test the claim also by constructing an appropriate confidence interval.
c. Does the interval capture 0? Relative to accuracy of orders, does either restaurant chain appear to be better?

Accuracy of Fast Food Drive-Through Orders In a study of Burger
King drive-through orders, it was found that 264 orders were
accurate and 54 were not accurate. For McDonald’s, 329 orders were
found to be accurate while 33 orders were not accurate (based on
data from QSR magazine). Use a 0.05 significance level to test the
claim that Burger King and McDonald’s have the same accuracy
rates.

In a study of fast
food accuracy on drive-thru orders, Burger King had 264 accurate
orders and 54 that were not accurate.
a) Construct a 95% CI
for the percentage of orders that are not accurate.
b) A similar survey at
Wendy's yielded a 95% CI of inaccurate orders of 6.2% < p <
15.9%. Comparing the two results, what do you find?

In a study of the accuracy of fast food drive-through orders,
McDonald's had 33. orders that were not accurate among 362 orders
observed (based on data from QSR magazine). Construct a 95%
confidence interval for the proportion of orders that are not
accurate. What would be the sample sizes needed to get a 95%
confidence interval of plus or minus 3% given that the initial
estimate of the population proportion is either 1%, 25%, 50%, 75%
or 99% (calculate the...
