Small Sample Size The dataset imagpop contains information about 10000 people from an imaginary population. One of the variables is math, which indicates whether the individual was a mathematics major. You can see the distribution of math majors in the population in the row percents shown below: rowPerc(xtabs(~math,data=imagpop)) ## no yes Total## 95.37 4.63 100.00 Suppose you were interested in the following Research Question: Are quantitative skills an important part of your job? You decide to quickly take a simple random sample of size 10 from this population. You can see the distribution of math majors in the sample below: set.seed(2014)smallsamp<-popsamp(n=10,pop=imagpop)rowPerc(xtabs(~math,data=smallsamp)) ## no yes Total## 100 0 100 Which of the following statements best describes a problem that may arise in this scenario?

USE DESCRIPTIVE STATS A report shows that Covid-19 reduced household expenditure in Europe by 8% in 2020. Elsewhere, consumer spending also dropped significantly in 2020, with 4% seen in the United States, and 17% reported in China (Broom, 2021).After reading the report, Mr. Goh, a student of Singapore University of Social Sciences, was interested to find out how Covid-19 has affected the household spending in Singapore. Surprisingly, he found news saying that consumer spending among Singapore residents was resilient and at a similar level to 2019 (Choo, 2021).In order to have a better understanding of the impact of Covid-19 on household spending of Singapore residents, Mr. Goh decided to conduct a survey. He got a random sample of 32 students from Singapore University of Social Sciences, and collected data on their average monthly household expenditure in 2019 and 2020. Based on his own experience, he hypothesised that the household expenditure of Singapore residents in 2020 is lower…

edo exercises 17 and 18 in section 8.1 of your textbook, about the small animal who lives in an area with woods and meadows, using the following data:If the animal is in the woods on one observation, then it is twice as likely to be in the woods as the meadows on the next observation. If the animal is in the meadows on one observation, then it is three times as likely to be in the meadows as the woods on the next observation.Assume that state 1 is being in the meadows and that state 2 is being in the woods.(1) Find the transition matrix for this Markov process. (2) If the animal is initially in the woods, what is the probability that it is in the woods on the next three observations? (3) If the animal is initially in the woods, what is the probability that it is in the meadow on the next three observations?
