Below are three binary ciphertexts resulting from encrypting three ASCII-encoded plaintexts with a stream cipher, all with the same stream cipher key. Your goal is to decrypt the first character of the last ciphertext (C3). 1) Demonstrate your steps to derive the decrypted character. 2) Explain why we have to use a one-time pad for encryption.Ciphertext1: 11011111…Ciphertext2: 10100111…Ciphertext3: 10001111…ASCII Table 000000010010001101000101011001110000NULDLESP0@P·p0001SOHDC1!1AQaq0010STXDC2″2BRbr0011ETXDC3#3CScs0100EOTDC4$4DTdt0101ENQNAK%5EUeu0110ACKSYN&6FVfv0111BELETB’7GWgw1000BSCAN(8HXhx1001HTEM)9IYiy1010LFSUB*:JZjz1011VTESC+;K[k{1100FFFS, N^n~1111SIUS/?O_oDEL

The box plot (box and whisker) of Credit Card Balance is below.

Continuing to focus on Credit Card Balance (Column E). Calculate the 5-number summary for Credit Card Balance (Column E).

Use the data from Table 1 below to answer questions 7–20. Table 1 shows data of 20 people surveyed about their current credit card balances. The data set includes variables regarding an individual’s gender, ethnicity, age, current credit card balance, and the number of credit cards they currently have open.
