Suppose you want to test the claim that a population mean equals 44.

(a) State the null hypothesis.

-H0: μ > 44

-H0: μ < 44

-H0: μ = 44

-H0: μ ≠ 44

-H0: μ ≥ 44

(b) State the alternate hypothesis if you have no information regarding how the population mean might differ from 44.

-H1: μ > 44

-H1: μ < 44

-H1: μ = 44

-H1: μ ≠ 44

-H1: μ ≥ 44

(c) State the alternative hypothesis if you believe (based on experience or past studies) that the population mean may exceed 44.

-H1: μ > 44

-H1: μ < 44

-H1: μ = 44

-H1: μ ≠ 44

-H1: μ ≥ 44

(d) State the alternative hypothesis if you believe (based on experience or past studies) that the population mean may be less than 44.

-H1: μ > 44

-H1: μ < 44

-H1: μ = 44

-H1: μ ≠ 44

-H1: μ ≥ 44

1. Bill Alther is a zoologist who studies Anna's hummingbird (Calypte anna). (Reference: Hummingbirds, K. Long, W. Alther.) 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. 3.7 2.9 3.8 4.2 4.8 3.1 The sample mean is = 3.75 grams. Let x be a random variable representing weights of hummingbirds in this part of the Grand Canyon. We assume...

It is claimed that the mean of a population equals 200. You test this claim by taking a sample of size n = 144. The mean of the sample is calculated to equal 205. Somehow, it is known that the standard deviation of the population of interest is 15. Does the evidence from the sample support the claim, or does it appear that the population mean is not equal to 200? Test at the five percent level. a.) Test this...
