A sociologist claims the probability that a person picked at random in Grant Park in Chicago is visiting thearea is 0.34. You want to test to see if the proportion different from this value.To test the hypothesis that the proportion is different from the given value, a random sample of 21 peopleis collected.If the number of people in the sample that are visiting the area is anywhere from 7 to 10 (inclusive)we will not reject the null hypothesis that pOtherwise, we will conclude that p + 0.34.0.34.Round all answers to 4 decimals.1. Calculate a =P(Type I Error) assuming that p0.34. Use the Binomial Distribution.%3|2. Calculate B = P(Type II Error) for the alternative p0.25. Use the Binomial Distribution.3. Find the power of the test for the alternative p0.25. Use the Binomial Distribution.

Suppose that you are studying the number of vehicles owned by a US household. You find that the average is 1.9 vehicles per household with a standard deviation of 2.8 vehicles per household. What is the most likely shape for the population described above? Find the probability that 40 randomly selected households have an AVERAGE number of vehicles greater than 2.5.
Suppose the random variable X has a population mean u=20 and a population standard deviation o=9. If a random sample n=81 is taken, what is the probability that the sample mean is between 18 and 21.5?
A courier service company wishes to estimate the proportion of people in various states that will use its services. Suppose the true proportion is 0.050.05. If 216216 are sampled, what is the probability that the sample proportion will differ from the population proportion by less than 0.040.04? Round your answer to four decimal places.
Mensa requies a test score to be in the top 2%. The test has a mean of 100 and Std. Dev. of 15.and scores are normally distributed. If 4 subjects take the test and they have a mean of 132 but the individual scores are lost, can we conclude that all 4 of them are eligible for Mensa?
If the p-value on a coin flip experiment is .002. What would you conclude? Group of answer choices The coin is unfair. The probability of getting the proportion that you did or something more remote is 0.002. The coin is unfair. The probability of the coin being unfair is 0.002. The coin is fair. The probability of the coin being unfair is 0.002. The coin is fair. The probability of getting the proportion that you did or something more remote is 0.998.
Suppose that you make a large number of independent observations of a random variable and then construct a table giving the possible values of the random variable and the proportion of times each value occurs. What will this table resemble?
Suppose you did an experiment with 3 groups and 16 subjects per group. The sample variances in the three groups were 14, 16, and 18. Using Tukey's test to compare the means, what would be the two-tailed probability for a comparison of the first mean (14) with the last mean (18)?
About 71% of all female heart transplant patients will survive for at least 3 years. Eighty female heart transplant patients are randomly selected. What is the probability that the sample proportion surviving for at least 3 years will be pq less than 63%? Assume the sampling distribution of sample proportions is a normal distribution. The mean of the sample proportion is equal to the population proportion and the standard deviation is equal to The probability that the sample proportion surviving for at least 3 years will be less than 63% is (Round to four decimal places as needed.)

Suzette does an experiment where she collects date from 5 women snd obtains the scores: 4, 4, 5, 2, 5. She hypothesizes that the population mean for the population from which these scores are drawn is 3. She wants to test whether this hypothesis is true. What is the alternative hypothesis she is testing?
Aurah wanted to know the distribution of the number of students with blood type O. She randomly selected six students and recorded their blood type. Suppose the probability of a student having blood type O is 0.45 and X be the number of students with blood type O. Which of the following is(are) TRUE about the experiment? A. It is a Bernoulli experiment with probability of success equal to 0.45B. The success in this experiment is observing six students with blood type O.C. X-Bin(6.0.45)D. A single trial of the experiment corresponds to six students.
