Acar is traveling at a rate of 60 miles per hour. let d represent the distance traveled and h the number of hours of travel. which student modeled the situation correctly?
natalia’s work h = m + 60
tam’s work 60h = d
benito’s work 60d = h
jolon’s work m = 60 – h

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).
