(Short-answer) b. Continue from the previous question. Suppose part of the data you extracted from the data warehouse is the following. Identify the missing values you think exist in the dataset. Use Column letter and Row number to refer to each missing value in the dataset. Please write down how you want to address each particular missing value (you can group them if they receive same treatment). For imputation, you do not need to calculate the exact imputed values but just describe what kind of value you want to use to impute.

- I have a few questions I need help with Statement: When we build a nearest neighbor model, we shall not remove the redundant dummies when coding a categorical variable. True or False Statement: One reason why a neural network model often requires a significant number of data observations to train is that it often has a significant number of model parameters to estimate even if there are only a few predictors. True or False.

For coding simplicity, follow each output integer by a space, including the last one. Then, output a newline. Ex: If the input is: 2 4 6 8 10 12 14 16 18 20 the output is: 20 18 16 14 12 10 8 642 To achieve the above result, first read the integers into an array. Then output the array in reverse. 623802 1031906 nx3zmv7.arrow_forward6.3B-2. Multiple Access protocols (2). Consider the figure below, which shows the arrival of 6 messages for transmission at different multiple access nodes at times t=0.1, 0.8, 1.35, 2.6, 3.9, 4.2. Each transmission requires exactly one time unit. 1 2 3 4 t=0.0 t=1.0 t=2.0 t=3.0 5 6 t=4.0 t=5.0 For the slotted ALOHA protocol, indicate which packets are successfully transmitted. You can assume that if a packet experiences a collision, a node will not attempt a retransmission of that packet until sometime after t=5. 1 2 3 4 5 Karrow_forward
