- A researcher is comparing the effectiveness of three devices designed to help people who snore. There are 120 people who snore participating in the experiment. Using a table of random digits, the researcher will randomly place the participants into three equally sized treatment groups suitable for comparison. How many unique random numbers need to be selected from the table of random digits? 3 40 80 120Suppose that three of your family (ex: mother,father and you) drop their cell phones at your house and that each of them picks up the cellphone at random, list the elements of the sample space S using using the letter O and N for own phone and not his/her own phone to be picked, respectively. To each sample point assign a value x of the random variable X representing the number of people who get their right cell phone . Complete the table below.In a large clinical trial, 392,553 children were randomly assigned to two groups. The treatment group consisted of 195,331 children given a vaccine for a certain disease, and 36 of those children developed the disease. The other 197,222 children were given a placebo, and 129 of those children developed the disease. Consider the vaccine treatment group to be the first sample. Identify the values of n1, p1, q1, n2, p2, q2, p, and q.
- 2. In a population it is estimated that 20% have a desired trait of interest for the researcher. The researcher wants to know how many people on average he has to draw from a population to get 2 people with the trait. Use rows 20-24 of the Random Number Table to carry out the simulation. Explain clearly how you set up the problem and report your findings. Answer:A normal six-sided die is thrown once. The number of outcomes in the sample space isIn a large clinical trial, 401,476children were randomly assigned to two groups. The treatment group consisted of 202,144 children given a vaccine for a certain disease, and 29 of those children developed the disease. The other 199,332 children were given a placebo, and 113 of those children developed the disease. Consider the vaccine treatment group to be the first sample. Identify the values of n1, p1, q1, n2, p2, q2, p, and q. n^1=
- You draw two marbles without replacement from a bag containing three green marbles and four black marbles. The number of possible outcomes in the sample space isAn experiment is performed where a 3-color spinner is spun and then a 4-sided die is rolled. The possible outcomes for each event are red (R), blue (B), and yellow (Y) for the 3-color spinner and 1, 2, 3, and 4 for the 4-sided die. Identify the sample space for this experiment.A dowser has correctly located water for a well 1 out of 2 times in Jones County. In Jones County, someone who is just guessing has a 40% chance of locating water for a well. Does this sample provide sufficient evidence that the dowser can locate water and is not just guessing?
- In a large clinical trial, 401,321 children were randomly assigned to two groups. The treatment group consisted of 201,186 children given a vaccine for a certain disease, and 30 of those children developed the disease. The other 200,135 children were given a placebo, and 100 of those children developed the disease. Consider the vaccine treatment group to be the first sample. Identify the values of n1, p1, q1, n2, p2, q2, p, and q. = Round each to 8 decimalsA coin is flipped once. If the result is a heads, the coin is flipped 2 more times, and the result (heads or tails) of each successive flip is noted. If the result is a tails, the coin is flipped 3 more times and the result of each successive flip is noted. How many possible outcomes are in the sample space of this experiment?
