A random sample of 41 adult coyotes in a region of northern Minnesota showed the average age to be x = 2.07 years, with sample standard deviation s = 0.80 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. LA USE SALT (a) What is the level of significance?

(Round your answer to two decimal places.) Recall that Benford's Law claims that numbers chosen from very large data files tend to have "1" as the first nonzero digit disproportionately often. In fact, research has shown that if you randomly draw a number from a very large data file, the probability of getting a number with "1" as the leading digit is about 0.301. Now suppose you are an auditor for a very large corporation. The revenue report involves millions of numbers in a large computer file. Let us say you took a random sample of n = 217 numerical entries from the file and r = 52 of the entries had a first nonzero digit of 1. Let p represent the population proportion of all numbers in the corporate file that have a first nonzero digit of 1. LA USE SALT (a) Test the claim that p is less than 0.301. Use a = 0.10.

A large survey of countries, including the United States, China, Russia, France, Turkey, Kenya, and others, indicated that most people prefer the color blue. In fact, about 24% of the population claim blue as their favorite color. Suppose random sample of n = 59 college students were surveyed and / = 13 of them said that blue is their favorite color. Does this information imply that the color preference of all college students is different (either way) from that of the general population? Use a = 0.05.

P-value =The following is based on information from The Wolf in the Southwest: The Making of an Endangered Species, by David E. Brown (University of Arizona Press). Before 1918, the proportion of female wolves in the general population of all southwestern wolves was abo 509%. However, after 1918, southwestern cattle ranchers began a widespread effort to destroy wolves. In a recent sample of 36 wolves, there were only 8 females. One theory is that male wolves tend to return sooner than females to their old territories, where the predecessors were exterminated. Do these data indicate that the population proportion of female wolves is now less than 509% in the region? Use a = 0.01. Solve the problem using the critical region method of testing. Since the sampling distribution of p is the norm distribution, you can use critical values from the table below. Hypothesis Testing, Critical Values zo Level of Significance 1 = 0.05 ( = 0.01 Critical value zo for a left-tailed test -1.645 -2.33 Critical value zo for a right-tailed test 1.645 2.33 Critical value Zo for a two-tailed test $1.96 $2.58 USE SALT State the null and alternative hypotheses.
