Cost of Braces The average cost for teeth straightening with metal braces is approximately $534]. A nationwide franchise thinks that its cost is below that gure. A random sample of 25 patients across the country had an average cost of $5251 with a standard deviation of $630. At a=0.10, can it be concluded that the mean is less than $5341? Use the Pvalue method. Assume that the population is approximately normally distributed. Use a 11-83 Plus/T 1-84 Plus calculator. (a) State the hypotheses and identify the claim. H0. .|:'$- E... v This hypothesis test is a test. (b) Find the P-value. Round the answer to at least four decimal places. P-value = D
