Textbook Question
Chapter 4, Problem 49C
Consider the following “justification” that the Fibonacci function, F(n) is O(n): Base case (n ≤ 2): F(1) = 1 and F(2) = 2.
Induction step (n > 2): Assume claim true for n′ < n. Consider n. F(n) = F(n − 2) + F(n − 1). By induction, F(n − 2) is O(n − 2) and F(n − 1) is O(n − 1). Then, F(n) is O((n − 2) + (n − 1)), by the identity presented in Exercise R-4.16.
Therefore, F(n) is O(n).
What is wrong with this “justification”?

1. Smart Home Automation:o Connect a temperature sensor and a fan to a home gateway.o Configure the home gateway so that the fan is activated when the temperature exceedsa set threshold (e.g., 30°C).2. WiFi Network Configuration:o Set up a wireless LAN with a unique SSID.o Enable WPA2 encryption to secure the WiFi network.o Implement MAC address filtering to allow only specific clients to connect.3. WLC Configuration:o Deploy at least two wireless access points connected to a Wireless LAN Controller(WLC).o Configure the WLC to manage the APs, broadcast the configured SSID, and applyconsistent security settings across all APs.
using r language for integration theta = integral 0 to infinity (x^4)*e^(-x^2)/2 dx (1) use the density function of standard normal distribution N(0,1) f(x) = 1/sqrt(2pi) * e^(-x^2)/2 -infinity <x<infinity as importance function and obtain an estimate theta 1 for theta set m=100 for the estimate whatt is the estimate theta 1? (2)use the density function of gamma (r=5 λ=1/2)distribution f(x)=λ^r/Γ(r) x^(r-1)e^(-λx) x>=0 as importance function and obtain an estimate theta 2 for theta set m=1000 fir the estimate what is the estimate theta2?
