A random sample of 46 adult coyotes in a region of northern Minnesota showed the average age to be x = 2.03 years, with sample standard deviations = 0.76 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 a = 0.01. USE SALT (a) What is the level of significance? State the null and alternate hypotheses. Ho: < 1.75 yr; H₁: = 1.75 yr O Ho: > 1.75 yr; H₁: = 1.75 yr O Ho: = 1.75 yr; H₁: > 1.75 yr Ho: = 1.75 yr; H₁: < 1.75 yr O Ho: = 1.75 yr; H₁: ## 1.75 yr (b) What sampling distribution will you use? Explain the rationale for your choice of sampling distribution. O The Student's t, since the sample size is large and o is unknown. O The standard normal, since the sample size is large and o is known. O The standard normal, since the sample size is large and o is unknown. O The Student's t, since the sample size is large and a is known. What the of the sampl (c) Estimate the P-value. OP-value> 0.250 O 0.100 < P-value < 0.250 O 0.050 < P-value < 0.100. O 0.010 P-value < 0.050 OP-value < 0.010 statistic? (Round your answer to three ces.)
