Please answer the folllowing question, consider the binary communication channel in which 0 and 1 are equally likely to be sent. The signal is given below. The receiver calculates the decision varibale R and applies the following decision rule. Find the expression for the porbability density function of R given that a 0 was transmitted.

Probability Density Functions This exercise uses the normal probability density function and requires the use of either technology or a table of values of the standard normal distribution. The cash operating expenses of the regional phone companies during the first half of 1994 were distributed about a mean of $29.83 per access line per month, with a standard deviation of $2.25. Company A's operating expenses were $28.00 per access line per month. Assuming a normal distribution of operating expenses, estimate...
