Intermediate Statistics and Research Methods


Q1 (2).png

The accompanying data are drive-through service times (seconds) recorded at a fast food restaurant during dinner times. Assuming that dinner service times at the restaurant's competitor have standard deviation

sec, use a

significance level to test the claim that service times at the restaurant have the same variation as service times at its competitor's restaurant. Use the accompanying data to identify the null hypothesis, alternative hypothesis, test statistic, and P-value. Then state a conclusion about the null hypothesis.
