Suppose that in a remote part of the Grand Canyon, a random sample of six of these birds was caught, weighed, and released. The weights (in grams) were as follows. The sample mean weight of the six birds sampled is x-bar = 3.75 grams. Let x be a random variable representing weights of hummingbirds in this part of the Grand Canyon. We assume that x has a normal distribution and o = 0.96 gram. Suppose it is known that for the population of all hummingbirds, the mean weight is u = 4.80 grams. Does the data indicate that the mean weight of these birds in this part of the Grand Canyon is less than 4.80 grams? Use a 10% level of significance. a.) What is a? State the null and alternate hypotheses. Will you use a left-tailed, right-tailed, or two- tailed test? a = Ho: H = H1: / Select an answer v The test is a Select an answer v test b.) Identify the Sampling Distribution you will use. What is the value of the test statistic? The best sampling distribution to use is the |Select an answer v| distribution. The test statistic (z or t value) is = c.) Find or estimate the P-value for the test. The p-value is = Una poesia itali..docx MacBook Pro
