- In a test of a gender-selection technique, results consisted of 232 baby girls and 256 baby boys. Based on this result, what is the probability of a girl born to a couple using this technique? Does it appear that the technique is effective in increasing the likelihood that a baby will be a girl? The probability that a girl will be born using this technique is approximatelyU (Type an integer or decimal rounded to three decimal places as needed.) Does the technique appear effective in improving the likelihood of having a girl baby? O Yes O NoDraw a punnet square for number 5Studies are being done by different pharmaceutical companies in their search for the COVID-19 vaccine. Suppose that "Goodbye COVID-19." a possible candidate for the vaccine is under study. This is given to patients admitted to different Philippine hospitals diagnosed with COVID-19. Researchers are interested in getting the mean length of days patients are in quarantine facility before they are cleared of the virus. They started giving the vaccine to two different sets of 50 patients from the onset of their illness until they are cured. The data collected was submitted to the Department of Science and Technology for evaluation. In this study, what is the parameter? a. two different sets of 50 COVID-19 patients b. number of patients with COVID-19 c. total number of hospitals admitting COVID-19 patients d. mean length of days patients under study are in quarantine facility
- Due to Covid-19 pandemic, the demand for disposable medical face mask has increased drastically. A particular brand of medical face mask making machine is used to produce disposable medical face masks in mass production. This machine is capable of producing 80 to 100 industry standard surgical style face masks every minute. This particular machine has a 2% defective rate. The production of medical face masks on this machine is considered a random process where each produced mask is independent of the others. Using this information calculate the following probabilities: a) What is the probability that the 10th medical face mask produced is the first with a defeci. b) What is the probability that the face mask making machine produces no defective mask in a batch of 100? ( ) c) On average, how many face masks would you expect to be produced before the first defective mask? What is the standard deviation? (. d) Another brand of this machine that also produces surgical style face masks has…What is the absolute difference in the probbility of being less 4 in a triangular distribution with a minimum of 1 and a maximum of 11 and a most likely value of 8 and a beta distribution with the same minimum and maximum and an alpha = beta= 4?Let E and F be two events of an experiment with sample space S.
