A survey that included a request for an e-mail address was mailed to 30,000 people. Assume that for such surveys, the percentage of responses with an e-mail address is 4 %. If the goal of the survey was to acquire a bank of at least 11501150 e-mail addresses, find the probability of getting at least 1150 responses with e-mail addresses

P Bands will randomly survey people around various parts of campus. The survey taker, Jorge, wants to find people who attended a P Band performance last semester. From previous surveys, Jorge knows that the probability a person on campus did not attend a P Band performance last semester was 0.68. a) Let B be the number of people surveyed until the representative finds a person who did attend a P Band performance last semester. What is the distribution, parameter(s) and...

B. A nation-wide survey included 108 people from the Northeast region, 144 people from the West region, 216 from the South region, and 132 people from the Midwest region. The survey asked people whether or not they approved of a particular government program. 81 people from the Northeast approved, 81 people from the West approved, 162 people from the South approved, and 126 people from the Midwest approved. Assume the sample use for the survey is an accurate model of...

In a survey of 300 people, approximately 15% of the people identified themselves as being left-handed. What are the mean, standard deviation, and shape of the distribution of thesample proportion p-hat of respondents who say they are left-handed? (3 points) Using the normal approximation without the continuity correction, sketch theprobability distribution curve for the distribution of p-hat. Shade equal areas onboth sides of the mean to show an area that represents a probability of .95,and label the upper and lower...

Follow these discussion guidelines: For your initial post, conduct a survey of at least 4 people (you can use classmates). Choose one of the following surveys: 1. Ask participants how many siblings they have. 2. Ask participants how many slices of pizza can eat. 3. Ask participants how many pairs of shoes they own. All students will create a discrete probability distribution using the data. X represents the individual data values and P(x) represents the probability of the individual solution....

A. According to a 2009 Reader's Digest article, people throw away about 10% of what they buy at the grocery store. Assume this is the true proportion and you plan to randomly survey 192 grocery shoppers to investigate their behavior. What is the probability that the sample proportion does not exceed 0.18? Note: You should keep at least 4 decimal places for any intermediate calculations you make to match wamap's approach and calculations. Answer = (Enter your answer as a number...
