(b) Find the critical value(s). Round the answer(s) to at least three decimal places. If there is more than one critical value, separate them with commas. Critical value(s): D (c) Compute the test value. Always round t score values to at least three decimal places. \"D :1 \fPart: 4 / 5 Part 5 of 5 (e) Summarize the results. There is enough evidence to support the claim that the nationwide franchise's mean cost for teeth X straightening is less than $5496.Cost of Braces The average cost for teeth straightening with metal braces is approximately $5406. A nationwide franchise thinks that its cost is below that figure. A random sample of 26 patients across the country had an average cost of $5230 with a standard deviation of $629. At a= 0.005, can it be concluded that the mean is less than $5406? Assume that the population is approximately normally distributed.
