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 10 phones from the manufacturer had a mean range of 1180 feet with a standard deviation of 41 feet. A sample of 20 similar phones from its competitor had a mean range of 1110 feet with a standard deviation of 35 feet. Do the results support the manufacturer's claim? Let ; be the true mean range of the manufacturer's cordless telephone and 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 2 of 4: Compute the value of the I test statistic. Round your answer to three decimal places.
