To further investigate this claim, a researcher recorded reporting time and leaving time of all 150 mothers who had come for ANC at IHK from 11th to 15th September 2014. He calculated the mean waiting time as 67 minutes with a standard deviation of 63 minutes. In the study, he assumed a 95% level of confidence. a) Demonstrate this information with a normal distribution sketch drawing b) State the Null and Alternative hypothesis (drawing the respective standardized normal distribution curve and indicating the critical value and region) a) It will take more than 90 minutes to attend to a pregnant mother
