Question 15 (1 point). Which of the following statements is TRUE? Random change of allele frequencies over several generations in a very large population of wild pigs could be an example of genetic drift. Changes in allele frequencies caused by some individuals in a population surviving better than others one month after a hurricane could be an example of genetic drift. Random changes in allele frequencies caused by a few individuals starting a new population on an island could be an example of natural selection. A random mutation causing a male to have a new phenotype that is preferred by many females in the population could be an example of genetic drift. Populations in which natural selection is not occurring are more likely to undergo genetic drift.

A company that makes dog treats is investigating whether a dog's size affects if the dog enjoys the treat or not. The company asked 150 dog owners if their dog enjoyed the chicken-flavored chew sticks. Their responses are given in the following table. Dog Size Enjoyed Did Not Enjoy Small 17 18 Medium 14 21 Large 34 46 If one response is selected at random, what is the probability the response indicated that the dog is small-sized given that they enjoyed the treat? Express your answer as a fraction in lowest terms or a decimal rounded to the nearest millionth. Answer 3 Points
Based on the sociological imagination, a term proposed by C. Wright Mills, how would an individual view a Little League baseball game?
Design of Digital IIR Filter: A DSP engineer has been assigned to design and implement a lowpass filter (LPF) that has a 0.5 dB ripple in the passband, an attenuation of 74 dB for Omega >= Omega 𝑠, a passband frequency of Fp = 1 kHz, and a stopband frequency of Fs = 1.24 kHz. (a) Determine the order, poles, and transfer function for Type I lowpass Chebyshev (analog filter). You may compute the poles by considering 𝑆𝑘 Omega 𝑐 . Show all the steps in detail. (b) Convert the analog filter into a digital IIR filter using the bilinear transformation when T = 1
Suppose that the yield corresponding to 1y, 1.5y, 2y and 2.5y are 4%, 4.5%, 4.75% and 5% respectively. Consider a swaption which gives the holder a right to pay 5% in 18 month swap starting in 1 year's time. The volatility of swap rate is 20%. Payments are made semi-annually and principal is £100. Find the price of the swaption in terms of cumulative normal distribution function.
What can happen if the CA is compromised by an attacker? Choose all that apply. The attacker is able to decrypt cipher exchanged (and recorded by the attacker) between Alice and Bob, even if the cipher was recorded before the CA is compormised. The attacker is able to impersonate Bob to Alice. The attacker can learn the key that was used between Alice and Bob (the true Bob) in previous conversations.

The equilibrium quantity is Litres per day. For Part A: When the price was $1.60 per Litre, The quantity demanded was 2500 - 1250(1.60) = 2500 - 2000 = 500 Litres per day. The quantity supplied was 1250(1.60) - 1250 = 2000 - 1250 = 750 Litres per day. The amount demanded is equal to the amount supplied. For Part B: When the price was $1.30 per Litre, The quantity demanded was 2500 - 1250(1.30) = 2500 - 1625 = 875 Litres per day. The quantity supplied was 1250(1.30) - 1250 = 1625 - 1250 = 375 Litres per day. The amount demanded is greater than the amount supplied. Suppose that a highly contagious virus begins to spread throughout the population and residents are required to stay at home. As such, the new demand for petrol (D) is given by the following equation. Note that supply conditions remain unchanged for the meantime. D' = 2000 - 1250P
