A manufacturer claims that the calling range (in feet) of its 900-MHz cordless telephone is greater than that of its leading competitor. A sample of ii phones from the manufacturer had a mean range of 1350 feet with a standard deviation of 24 feet. A sample of 18 similar phones from its competitor had a mean range of 1340 feet with a standard deviation of 45 feet. Do the results support the manufacturer's claim? Let u, be the true mean range of the manufacturer's cordless telephone and u: be the true mean range of the competitor's cordless telephone. Use a significance level of a = 0.01 for the test. Assume that the population variances are equal and that the two populations are normally distributed. Step 1 of 4: State the null and alternative hypotheses for the test.

Question
A manufacturer claims that the calling range (in feet) of its 900-MHz cordless telephone is greater than that of its leading competitor. A sample of 11 phones from the manufacturer had a mean range of 1350 feet with a standard deviation of 24 feet. A sample of 18 similar phones from its competitor had a mean range of 1340 feet with a standard deviation of 45 feet. Do the results support the manufacturer's claim? Let uj be the true mean range of the manufacturer's cordless telephone and 42 be the true mean range of the competitor's cordless telephone. Use a significance level of a = 0.01 for the test. Assume that the population variances are equal and that the two populations are normally distributed. Step 1 of 4: State the null and alternative hypotheses for the test.
