(Use Poisson Distribution) A fast-food restaurant is trying to hire employees. Let’s assume that one employee can process 10 orders in 15 minutes. The company wants to prepare for orders occurring at that point with at least an 80% probability (For example, if 50 orders occur with a 70% probability in 15 minutes, and 60 orders occur with an 80% probability, the company wants to process at least 60 orders). The following data is the number of orders in 15 minutes. You can calculate the average number of orders using the following data. How many employees should the branch employ? (For example, if 61 orders are placed in 15 minutes, with an 80% probability, the branch should hire 7 employees.) 9:00 AM    9:15 AM    9:30 AM    9:45 AM    10:00 AM    10:15 AM    10:30 AM    10:45 AM    11:00 AM    11:15 AM    11:30 AM    11:45 AM    12:00 PM    12:15 PM    12:30 PM    12:45 PM    1:00 PM    1:15 PM    1:30 PM    1:45 PM    2:00 PM53    53    49    38    26    84    27    36    19    38    96    74    85    64    33    47    16    96    73    59    25

(Use Exponential Distribution) It is said that the average lifespan of a smartphone produced by a company is 4 years and follows an exponential distribution. Find the probability that this smartphone will last more than 7 years. Round to 4 decimal places. (for example, 0.0233333 should be written as 0.0233. If written as 2.3333%, the answer will be incorrect.)

Find the probability that this smartphone will last more than 6 years. Round to 4 decimal places. (for example, 0.0233333 should be written as 0.0233. If written as 2.3333%, the answer will be incorrect.)

Which of the following is used to measure the performance of a model on training data

[Use Exam1-Data.xlsx] Find the Z-score of the “PER” value of the observations for all years and companies, and find the skewness of the distribution of the values ​​excluding any outliers with Z-score higher than 3 or lower than -3 using filter. (For example, if 1 out of 10 observations is an outlier, you can discuss the distribution of the 9 observations after filtering out the 1. DO NOT REMOVE THE OBSERVATIONS)You can check the distribution with a clustered column chart. A left-skewed distribution means a distribution with a tail that is longer on the left than on the right. A right-skewed distribution means a distribution with a tail that is longer on the right than on the left. Normal distribution means a distribution that is not skewed in any way. Exam1_Data.xlsx
