Suppose a vote was conducted in a small town of 5000 people. Among a random sample of 100 votes, 55 were in favor of a proposition while 45 were against it. So the margin of victory of the proposition is estimated to be 10% = 55% − 45%. Denote by p the percentage of the votes in favor of the proposition. (a) Provide an estimate ˆp and construct a 95% confidence interval of p. (b) Express the estimated margin of...

30% of people between 60-70 years old will have at least one visit to a health provider. This proportion will be 5% for people between 10-20 years old, and it will be 15% for kids between 5-10 years old. If we randomly select 75 of people in the age range of 60-70, then answer the following questions: 1 What is the expected number of those who will visit a health provider? 2 What is the probability that at least 15...

2.A researcher believes that about 70% of the seeds planted with the aid of a new chemical fertilizer will germinate. He chooses a random sample of 140 seeds and plants them with the aid of the fertilizer. Assuming his belief to be true, approximate the probability that more than 97 of the 140 seeds will germinate. Use the normal approximation to the binomial with a correction for continuity. Round your answer to at least three decimal places. Do not round...

13.Suppose that 60% of people in the population support raising taxes to pay for wetlands preservation. Suppose you randomly sample 100 people and ask them whether they support raising taxes for this purpose. If you divide the number of people in your sample who support raising taxes by the total number of people asked (100), you obtain a random variable, let’s call it p̂. Use the central limit theorem to come up with the approximate probability that p̂ is within...

Two years ago “Illyria” decided to enter the chocolate market, and it began by producing vanilla flavored chocolate called “Vanchoc”. The company’s sales of chocolate are higher than expected, and consumers’ ratings of the product have a mean of 75 and a standard deviation of 25 on a 100-point scale for which 100 is the most favorable score and zero is the least favorable score. Past experience has also shown Illyria that a consumer who rates one of its products...
