Question 2 (4 points) In a certain Scandinavian population, it is suspected that 66% of individuals have blonde hair. You suspect that this percentage is actually higher. You take a random sample of 18 individuals from this population. Let X repre- sent the number of individuals in your sample who have blonde hair. Suppose you decide on a rejection region of {X > 15).

USE R STUDIO The stackloss data frame available in R contains 21 observations on four variables taken at a factory where ammonia is converted to nitric acid. The first three variables are Air.Flow, Water.Temp, and Acid.Conc. The fourth variable is stack.loss, which measures the amount of ammonia that escapes before being absorbed. Read the help file for more information about this data frame. - Give a numerical summarization of each column of the dataset, then use boxplots to help illustrating...

2nd pic is the answer of the 1st question
A graduate technologist has a clunker of a car that will probably run for two more years. The current trade-in value is $750. Next year, the car will be worth $375. In two years, it would have a scrap value of $150. Operating costs will be $2400 in the coming year and $3000 in the following year. A new car could be purchased for $7000. The technologist would keep the new...

Please answer using R studio
(1 point) Alzheimer's disease is a progressive disease of the brain. An article published in 2006 was critical of the methodology used in studies of Alzheimer's treatments conducted prior to 2006. In a random sample of n = 31 Alzheimer's studies, the quality of the methodology was measured on the Wong scale with scores ranging from 9 (low quality) to 27 (high quality) for each study. The data is provided below. data can be copied...

Plese use R-Studio to answer this question. qbinom(p, size, prob) gives the smallest x value so that the probability of being less than or equal to x is at least p. Try the following: pbinom(0:10, size=10, prob=0.5) ; qbinom(0.75, size=10, prob=0.5) What is the value for which 90 percent of the probability is smaller than it, when you flip a fair coin 20 times?
