Custоmer Arrivаls аt а DMV оffice are randоm and independent; the probability of an arrival in any time-slot of a ten-minute duration is the same as the probability of arrival in any other time slots of ten-minute duration. Based on historical data, on the average five customers are expected to arrive at this DMV office in a ten-minute slot. You are interested in improving the customer service process at the DMV office. We need to find the probability that no more than seven customers arrive at this DMV office in ten-minutes. What is the correct Excel formula (among the ones listed below) that will help us find the answer?
Questiоn 1: Explоrаtоry Anаlysis (9 points) (1а) (3 points) Using trainData, create a boxplot of Price and Gpu_brand, with Price on the vertical axis.Interpret the plot. Which Gpu brands for laptops are the most expensive? (1b) (3 points) Using trainData, perform an ANOVA F-test on the means of the three Gpu brands. State the alternative hypothesis. Using an α-level of 0.05, do we reject the null hypothesis that the means of the three Gpu brands are equal? Explain your conclusion. (1c) (3 points) Using "trainData" dataset, create a scatterplot matrix and a correlation table that includes the following continuous variables:i) Ppiii) Weightiii) HDDDoes there appear to be multicollinearity among these three variables? Include your reasoning.
