The result of a hypothesis is described in terms of the probability of obtaining a particular sample. Use the given context to formulate the null and alternative hypotheses. Discuss whether the sample provides evidence for rejecting the null hypothesis.A public bus company official claims that the mean waiting time for bus number 14 during peak hours is only 
Karen finds this hard to believe as she seems to be invariably late for work. For 42 randomly selected days, her mean waiting time for bus 14 during peak hours was 11.3 minutes. Assuming that the population mean waiting time is 10 minutes , the probability of selecting a random sample with a mean waiting time of 11.3
minutes or more is 0.0026. What will be an ideal response?
