Transcribed Image Text:Assume that Friday morning taxi-cab rides have times with a standard deviation of o=9.8 minutes. A cab driver records
times of rides during a Friday afternoon time period and obtains these statistics: n = 13, x= 17.7 minutes, s = 12.2
minutes. Use a 0.01 significance level to test the claim that these Friday afternoon times have greater variation than the
Friday morning times. Assume that the sample is a simple random sample selected from a normally distributed
population.
Let o denote the population standard deviation of Friday afternoon cab-ride times. Identify the null and alternative
hypotheses.
= 9.8
Ho: o
H₁: o
(Type integers or decimals. Do not round.)
Identify the test statistic.
> 9.8
18.60
(Round to two decimal places as needed.)
Identify the P-value.
