The Excel file " Servicelevel.xlsx " contains the time (in seconds) to answer 50 randomly selected incoming calls to a financial center a)At the 1% level of significance conduct a hypothesis test to determine there is enough evidence to conclude that the population proportion of calls answered in excess of 20 seconds at the center exceeds 10 % Illustrate your results with a graph below.b) Calculate the p-value and confirm the result of your test using the p-value approach. Show the p-value on the graph you drew in part (a). Using the p-value calculated, determine whether the outcome of your hypothesis test would have been different if the level of significance were 10% instead. Explain.these are the excel values
