Let f be the relation which takes as input a song title from the list, and which outputs the number of characters in the name of the album on which it appears (as listed on the table), excluding spaces. For example, f("Bad Guy") 32 characters (check this yourself). Similarly, f("Shape of You") = 1. 32 since the album title "When We All Fall Asleep, Where Do We Go?" has Is f a function? If so, is it one-to-one? Explain your answers. If it's one-to-one, explain in words (with some examples) what f-1 does.

Please solve subparts A,B and no reject. Because its no essay thank u Question This study aims to determine the need for SPKLU (public electric vehicle charging stations) or charging stations (CS) for owners of battery-based electric motorized vehicles (KBLBB) in Indonesia. Data for the year until the end of 2021 recorded as many as 800 KBLBB from various brands (Hyundai 700, BYD 24, Tesla 56, Nissan 20). There is a list of names of KBLBB owners according to the brand. It is suspected that the need for SPKLU differs according to the brand of the car. A. If the sample will be selected as many as 80 KBLBB owners. Determine the sampling technique that is in accordance with the population information above. And write down the steps / stages until 80 people are selected (choose 80 people out of 800 people) B. Explain the difference between random and non-random sampling techniques. And explain the sampling technique in each of these sampling techniques (randon and non-random)

Chapter 8, Problem 10 Aa Aa A random sample is selected from a normal population with a mean of u = 30 and a standard deviation of o = 8. After a treatment is administered to the individuals in the sample, the sample mean is found to be M = 33. If the sample consists of n = 16 scores, is the sample mean sufficient to conclude that the treatment has a significant effect? Use a two-tailed test with a = .05. If needed, use the Standard Normal Distribution tool to help you find the critical value.

He thinks the water is too warm and wants to cool the temperature down using ice cubes. He knows that each ice cube will lower the temperature of the birdbath by 3 degrees. He decides to add 7 ice cubes to the birdbath. What integer will represent the change in the birdbath's water temperature after adding the ice cubes? degrees 5 of 6 (-)

BMX racing is a sprint sport where races range from around 30 to 45 seconds depending on the length of the track. Given races are over in such a short time, the start - commonly referred to as gate starts due to everyone lining up on a gate, are critical to success in the sport. A coach with a particular interest in data analysis coaching an elite athlete records data at a local racetrack for the time it takes their athlete to reach the bottom of the starting hill. The coach has found that the hill times for their athlete follow a normal distribution with mean 2.3 seconds and standard deviation 0.02 seconds. (a) What hill time distinguishes the slowest 10% of hill times? (b) What is the probability that a randomly selected hill time is less than 2.27 seconds? (c) Let X be the number of hill times that are less than 2.27 seconds from 10 separate starts. Assuming the athlete is well rested between starts, what distribution might you consider X to follow. Justify your response by…
