- In a genetics experiment on peas, one sample of offspring contained 433 green peas and 121 yellow peas. Based on those results, estimate the probability of getting an offspring pea that is green. Is the result reasonably close to the value of 3/4 that was expected?To study the hormonal regulation of a metabolic line, albino rats are injected with a drug that inhibits the synthesis of proteins in the organism. In general, 8 out of 30 rats die from the drug before the experiment is over. If 10 animals are treated with the drug. What is the probability that 4 or fewer arrive alive at the end of the experiment? What is the probability that more than 8 will arrive alive at the end of the experiment? Note: Answer with at least 4 decimal placesAccording to the CDC, as of MAY 2021, it is suspected that 2% of the US population currently have active coronavirus. According to Johns Hopkins, a particular type of COVID test (RT-PCR), has a false negative rate of 20%. That is, if a person has COVID, and takes this test, there is a 20% chance of testing negative. The false positive rate is about 5%. That means that about 5% of people who don't have COVID will nonetheless test positive. Consider the following two-way table for 10,000 randomly selected people who were tested for COVID using (RT-PCR). Positive test Negative test Total Has COVID A 40 200 No COVID 490 B 9800 Total 10000 1. fill in the missing values in the table. A • B • C • D 2.

If Javier's test is positive for Covid-19, to the nearest 3rd decimal place, what is the probability that Javier actually has Covid-19 at the time of testing? O 0.677 O 0.324 O 0.500 O It cannot be from the given information. « Previous Next SimpfunFemale undergraduates in randomized groups of 15 took part in a self-esteem study. The study measured an index of self-esteem from the point of view of competence, social acceptance, and physical attractiveness. Let x1, x2, and x3 be random variables representing the measure of self-esteem through x1 (competence), x2 (social acceptance), and x3 (attractiveness). Higher index values mean a more positive influence on self- esteem. Variable Sample Mean Standard Deviation Population Size Мean 15 19.48 2.92 X1 X2 X3 (a) Find a 90% confidence interval for u1 - 42.

- The Philippine Red Cross says that about 11% of PH population has Type B blood. A blood drive is being held at your school. What is the probability that exactly 2 of the first 20 blood donors have Type B blood? [Select] Given this sample of blood donors, compute the expected number who have Type B blood. [Select]Suppose 10% of a city’s inhabitants have contracted Covid-19 but are asymptomatic (do not show any symptoms). A PCR test for detecting Covid will return a positive result for 90% of the people with asymptomatic Covid and is negative for 90% of people who are not infected. What is the probability that a person for whom the test result is negative, actually has indeed contracted Covid-19?A certain cancer screening is able to detect existing cancer with a probability of 97%.
