Question
A random sample of 51 adult coyotes in a region of northern Minnesota showed the average age to be x = 2.05 years, with sample standard deviation s = 0.86 years. However, it is thought that the overall population mean age of coyotes is = 1.75. Do the sample data indicate that coyotes in this region of northern Minnesota tend to live longer than the average of 1.75 years? Use = 0.01.
What is the value of the sample test statistic? (Round your answer to three decimal places.)
Find the P-value. (Round your answer to four decimal places.)
Explanation / Answer
The statistical software output for this problem is:
One sample T hypothesis test:
: Mean of population
H0 : = 1.75
HA : > 1.75
Hypothesis test results:
Hence,
Test statistic = 2.491
P - value = 0.0080
