Researchers analyze a new portable radiocarbon dating machine and determine that the machine will correctly predict the age ofan archaeological object within established tolerances 70% of the time. The machine's inventor wants to test this claim, believingthat her machine correctly predicts age at a greater rate.Let p represent the proportion of times that the new portable radiocarbon dating machine correctly determines the age of anarchaeological object to within the established tolerances. The inventor's null and alternative hypotheses are as follows.Но : р0.70На : р> 0.70The inventor takes a random sample of n = 100 archaeological objects for which the age is already known and uses her machineto determine the age of each object. The machine correctly determines the age of 78 of the objects in the sample.What is the value of the standardized test statistic?(Round to 2 decimal places)

Given that Sample size n =100 Favorable cases x =78 Sample proportion p^=x/n =78/100 =0.78

Answered: to determine the age of each object.…
