Question
A random sample of 46 adult coyotes from Northern Minnesota showed the average age to be
sample mean of 2.05 years. The population standard deviation is known to be o = 1.13 years
However, it is thought that the average age of coyotes is µ = 1.75 yearstest to see if the coyotes
in Northern Minnesota live longer than the national average of 1.75 years. Use 0.03 level of
significance.
When using the classical approach, whạt is the critical region (step 3)?
Anything less than or equal to z = 1.80
O Anything less than or equal to z = 1.88
O Anything greater to or equal to z = 1.88
O Anything greater to or equal to z = 1.80
