A survey asks 1100 workers, "Has the economy forced you to reduce the amount of vacation you plan to take this year?" Forty-six percent of those surveyed say they are reducing the amount of vacation. Ten workers participating in the survey are randomly selected. The random variable represents the number of workers who are reducing the amount of vacation. Decide whether the experiment is a binomial experiment. If it is, identify a success, specify the values of n, p, and q, and list the possible values of the random variable x. Is the experiment a binomial experiment? O No O Yes What is a success in this experiment? O Selecting a worker who is not reducing the amount of vacation O O Selecting a worker who is reducing the amount of vacation This is not a binomial experiment. Specify the value of n. Select the correct choice below and fill in any answer boxes in your choice. OA. n= OB. This is not a binomial experiment. Specify the value of p. Select the correct choice below and fill in any answer boxes in your choice. OA. p= (Type an integer or a decimal.) OB. This is not a binomial experiment.

Homework 7.2 1. Four students are randomly selected from an algebra class and asked whether they suffer from math anxiety. Find the sample space for the possible outcomes of the survey using a tree diagram.

claim: most adults would erase all of their personal information online if they could. A software firm survey of 403 randomly selected adult showed that 50% of them would erase all of their personal information online if they could. Find the value of the test statistic.

A small shop owner wants to see how much people are spending at her store, so she numbers all the receipts from the past week and uses a computer program to generate a list of 20 random numbers.  She samples the receipts that correspond to those numbers. What type of sample was taken?     convenience sample     simple random sample     systematic sample     cluster sample     quota sample     voluntary response sample

A bowl of candy contains 21 green, 8 white, and 16 orange candies. TWO candies are randomly selected from the bowl. d) Find the number in the sample space of this experiment.  n(S)= ?  Write your answer as a whole number. e) Find the probability of event E: selecting 1 white candy and 1 orange candy. p(E)= ? Write your answer as a percent rounded to one decimal place.

A store owner wants to know if he sells more sandals or sunglasses during the summer. He records the number of sales for both products for the entire month of June. What is the data-gathering technique used? A experiment randomized survey observational study D voluntary survey C

Find the indicated probability. Round to three decimal places.A company purchases shipments of machine components and uses this acceptance sampling plan: Randomly select and test 29 components and accept the whole batch if there are fewer than 3 defectives. If a particular shipment of thousands of components actually has a 7% rate of defects, what is the probability that this whole shipment will be accepted? Group of answer choices 0.280 0.546 0.668 0.190

Determine if the following probability experiment represents a binomial experiment. If not, explain why. If the probability experiment is a binomial experiment, state the number of trials, n, and probability of success, p. A basketball player who makes 86% of his free throws is asked to shoot free throws until he misses. The number of free throws attempted is recorded. Select the correct choice below and, if necessary, fill in the answer boxes to complete your answer. O A. Yes, because the experiment satisfies all the criteria for a binomial experiment, n = and p = (Type integers or decimals. Do not round.) O B. No, because the experiment is not performed a fixed number of times. O C. No, because the trials of the experiment are not independent since the probability of success differs from trial to trial. O D. No, because there are more than two mutually exclusive outcomes for each trial.

You are doing research on balance and fitness.  To complete this research you will need a watch with a second hand.  Identify a random sample of n = 12 men and n = 8 women.  You must answer this question: How do you establish that this sample is truly random? Have each subject perform the following task:   Have the subjects stand with their hands at their side, raise one knee, cross their ankle over the other knee, squat and bring their hands palms together in front of their chest. Time the subject until they put their foot back down on the floor.   b) Ask the following questions: i) How many days per week do they exercise? ii) What is their favorite exercise?   You will analyze your data and compute the following statistics for each group:   1) The Mean and standard deviation of the number of seconds the subject stayed balanced 2) The Median number of days per week exercised 3) The Mode of the favorite exercise 4) The 90% confidence interval of the mean   Construct a complete…
