This graph shows the relationship between the number of hours (h) a business operates and the total cost of electricity (c). Find the constant of proportionality (r) for this relationship. Using the value of h, enter an equation in the form of c=rh that represent the relationship between the number of hours (h) and the total cost (c).

Atextile fiber manufacturer is investigating a new drapery yarn, which the company claims has a mean thread elongation of 12 kilograms with a standard deviation of 0.5 kilograms. the company wishes to test the hypothesis upper h subscript 0 baseline colon mu equals 12 against upper h subscript 1 baseline colon mu less-than 12 using a random sample of n equals 4 specimens. calculate the p-value if the observed statistic is x overbar equals 11.8. round your final answer to five decimal places (e.g. 98.76543).
