An independent testing laboratory in Mississauga found that a random sample of 18 of the newest version routers delivered speed of 1.82 Gbps, on average, with a standard deviation of 0.11 Gbps. Test the manufacturer's claim using a 0.04 significance level. Assume that the speeds are approximately normally distributed as the histogram of the sample values is roughly symmetric and bell-shaped, so t-distribution is applicable for hypothesis testing. Round to 3 decimal places where appropriate. (a) State the null and alternative hypotheses; identify which hypothesis is the claim and what is the type of the test.
