The juror pool for an upcoming trial contains 100,000 individuals in the population who may be called for jury duty. Theproportion of the available jurors on the population list who are Hispanic is 0.44. A jury of size 8 is selected at random from thepopulation list of available jurors. Let X = the number of Hispanics selected to be jurors for this jury.Explain why this scenario would seem to satisfy the three conditions needed to use the binomial distribution.O They are satisfied because 1) the data are binary (Hispanic or not), 2) the probability of success is always 0.56 and 3) the trials are independent(the first selection does not affect the next; n < 10% of population size).O They are satisfied because 1) the data are binary (Hispanic or not), 2) the probability of success is always O.44 and 3) the trials are independent(the first selection does not affect the next; n < 10% of population size).O They are satisfied because 1) the data are binary (picked or not), 2) the probability of success is always 0.44 and 3) the trials are independent(the first selection does not affect the next; n < 10% of population size).%2324&36WET5

Suppose that 6% of a particular population have a particularly nasty disease. There is a test for the disease that correctly identifies those with the disease 98% of the time. However, the same test gives a false positive 1% of the time. Suppose that a random person from this population is given the test as part of a wellness exam. Give answers in decimal form rounded to 4 decimal places as needed. A. Suppose that a random person comes in for a wellness exam and tests positive for the disease. What is the probability that she actually has the disease? B. Suppose that a person comes in for a wellness exam and tests negative. What is the probability that this person does not have the disease? C. What proportion of the total population will test positive? D. What proportion of the total population will not have the disease and will test negative?
A humane society claims that less than 61% of households in a certain country own a pet. In a random sample of 700 households in that country, 399 say they own a pet. At a= 0.05, is there enough evidence to support the society's claim? Complete parts (a) through (c) below. (a) Identify the claim and state H, and Ha. Identify the claim in this scenario. Select the correct choice below and fill in the answer box to complete your choice. (Type an integer or a decimal. Do not round.) O A. The percentage households in the country' that own a pet is not %. O B. Less than % of households in the country own a pet. O C. More than % of households in the country own a pet.

We are interested in estimating the proportion of people that can identify Nebraska but not Vermont. In a class of 55 students, each student was requested to select a sample of 6 people, show each person a map of the US and ask the person to identify the states of Vermont and Nebraska. The following numbers are the counts that each student got, that is, each number is the count of people in the student sample of 6, that could identify Nebraska but not Vermont.3344010110020030002020001100002010000001000200000001010Note: You can cut and past these numbers into an excel spreadsheet to help you calculate the mean and the standard deviation and compute the confidence interval. If you have trouble pasting them, paste them to a text file first and then copy from there.When we collect all the students' data, we have a sample size of 6x55=330.Of the sample of 330 people, what proportion were able to locate Nebraska but not Vermont?

A certain medical school accepts only 8% of applicants. A prep program claims that their students are admitted to this medical school at a higher rate. To test their claim at the 10% significance level, we select at random 144 students from the prep program (who all apply to this medical school), and we compute p, the proportion of the sample who are admitted to the medical school.
Some students are sampled at random from the cohort at a certain university and their heights recorded. The university has a student cohort of 1000, and 100 students are sampled. Thirty students are 175cm, thirty are 160cm, fifteen are 163cm, ten are 180cm, ten are 158cm, and five are 170cm. To three significant figures, how many resamples of size 100 can one make from this data? 4.53 × 1058 3.72trillion 2.63 × 1051 135million 3.72 x 1048
3. At a factory that produces doorknobs, a batch of 1500 doorknobs has just been produced. To check the quality of the doorknobs, a random sample of 100 doorknobs is selected to test for defects. Out of these 100 doorknobs, 2 were found to be defective. Based on these results, what is the best estimate you can give for the number of defective doorknobs in the batch of 1500? Solve this problem in two different ways, explaining your reasoning in each case. just been
