Three different traffic routes are tested for mean driving time.
The entries in the table are the driving times in minutes on the
three different routes. At the 0.05 level of significance, are the
mean driving times similar regardless of routes?
Route 1: 30, 32, 27, 35
Route 2: 27, 29, 28, 36
Route 3: 16, 41, 22, 31
What statistical test are you going to run?
What is the null hypothesis?
What is the alternative hypothesis?
What is test statistic? Please answer with two decimal places.
What is the p-value? Please answer with two decimal places.
What is your conclusion based on the p-value and the level of significance?
What is the proper conclusion?

three different traffic routes are tested for mean driving time.
the entries in the table below are the driving times in minutes on
the three different routes. use an ANOVA to test the hypothesis.
Route 1: 30, 32, 27, 35 Route 2: 27, 29, 28, 36 Route 3: 16, 41,
22, 31 1) find the numerator degrees of freedom 2) find the
denominator degrees of freedom 3) find SS factor 4) find ss total
5) find the F statistic

A study compared three display panels used by air traffic controllers. Each display panel was tested for four different simulated emergency conditions.
A study compared three display panels used by air traffic controllers. Each display panel was tested for four different simulated emergency conditions. Twenty-four highly trained air traffic controllers were used in the study. Two controllers were randomly assigned to each display panel–emergency condition combination. The time (in seconds) required to stabilize the emergency condition was recorded. The resulting data and analysis results are given below.

Claim: there is no difference between the mean daily driving
time for the popuation of 16-20 year old men and the mean daily
driving time for the population of men 60 years and older. In a
study of times that people drive each day, it was found that 50 men
aged 16-20 years drove a daily average of 49.3 minutes with a
standard deviation of 21.4 minutes, and 55 men aged 60 years and
older drove a daily average of...
