Bill and Lisa are surveying their classmates about their summer reading. Their questions are given below: Bill: How many books were recommended by the book reading club this month? Lisa: How many books did you read from the recommended list? Who wrote a statistical question and why?  Lisa, because there can be only one answer to the question Bill, because there can be many answers to the question Lisa, because there will be variability in the responses collected Bill, because every student will give the same answer

What is the variable of interest in this data set and what is the type of this variable?

The scenario A professor wanted to learn more about the students at her university with regards to whether they prefer in-person or online classes. She randomly sent out surveys to  students at the university . Of the students that responded, % prefer taking online classes. The questions Use the information from the scenario to answer the following: What is the population that this study is trying to get information about? What is the variable used for the study? What type of variable is the variable in question 2? What is the sample statistic for this study? What is the parameter of interest for this study? (the population parameter they are trying to gather information about)

A recent study has shown that approximately 31.6% of Canadians are considered 'supertasters,' or people who experience the sense of taste with greater intensity than average. Consider a sample of 23 Canadians, each of whom are asked to indicate if they are a supertaster or not. Please use this information to answer the following questions.a. How many of the Canadians sampled can we expect to be supertasters?Answer:_______people. Round to at least FOUR digits after the decimal if necessary. b. What is the standard deviation of the number of people sampled who are supertasters?Answer:______people. Round to at least FOUR digits after the decimal if necessary.

Question for context: One way of checking for the effects of undercoverage, nonresponse, and other sources of bias in a sample survey is to compare the sample with known demographic facts about the population. The 2010 census found that 13.9%, or 32,576,000, of the 235,016,000 adults (aged 18 or older) in the United States identified themselves as being of Hispanic origin.  An opinion poll plans to interview 1500 adults at random. Find the probability that such a sample will contain between 12% and 16% adults of Hispanic origin. I'm not really sure how to solve this question and need some help!

Polls. America OnLine published a survey question. Among the 2,300 Internet users who responded, 20% answered “yes” and the others answered “no.” For the “yes” responses, what is the value of pn? What is fundamen-tally wrong with this survey?
