One of the Key Quality Characteristics in Many Service Environments

question 11

True/False

One of the key quality characteristics in many service environments is that the variation in service time be reasonably small.Recently,a major amusement park company initiated a new line system at one of its parks.It then wished to compare this new system with the old system in place at a comparable park in another state.At issue is whether the standard deviation in waiting time is less under the new line system than under the old line system.The following information was collected: Assuming that it wishes to conduct the test using a 0.05 level of significance,the null hypothesis should be rejected since the test statistic exceeds the F-critical value from the F-distribution table.

Definitions:

F-value

A ratio used in statistical analysis to determine the significance of groups of variables in tests like ANOVA.

P-value

The probability of observing data as extreme as, or more extreme than, what was actually observed, assuming the null hypothesis is true, used in hypothesis testing in statistics.

Confidence Coefficient

a measure of the reliability of an interval estimate, often expressed as a percentage indicating the frequency with which the true parameter is expected to fall within the interval.

Null Hypothesis

A hypothesis that suggests there is no significant difference between specified populations, any observed difference being due to sampling or experimental error.
